Enable an AI agent to recognise references to mainland China, establish their geographic and contextual scope, and decide whether a location-based inference or action is justified.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify.

Purpose and description
Enable an AI agent to recognise references to mainland China, establish their geographic and contextual scope, and decide whether a location-based inference or action is justified.
Mainland China is a context-dependent geographic and jurisdictional term generally referring to the territory administered by the People's Republic of China excluding Hong Kong and Macao, and excluding Taiwan and its administered islands, while ordinarily including Hainan and other PRC-administered offshore islands.
It can be Resolve a mention of mainland China to an explicit geographic interpretation.; Classify a location as included, excluded or unresolved under a selected source and date.; Compare mainland-China coverage across datasets while exposing differences in island and territorial treatment.; Display an attributed extent with appropriate uncertainty and disputed-boundary annotations.; Identify when an address-routing, reporting or service-eligibility decision requires a separate governing policy..
Distinguishing features
A reference to the People's Republic of China does not by itself establish that the intended extent is mainland China; the source's scope must be checked.
The conventional designation is not necessarily restricted to land physically connected to the Asian continent; Hainan is a useful test of the intended meaning.
Hong Kong and Macao are commonly distinguished from mainland China in institutional usage, so a source that includes them requires an explicit interpretation.
A reference to Taiwan must preserve the source's geographic or institutional distinction without converting that distinction into an unqualified sovereignty claim.
The designation identifies an area under a stated interpretation, rather than everyone who is Chinese or every place associated with Chinese culture.
Scope
+ Geographic and institutional meanings of mainland China and the contexts that distinguish them
+ Context-specific inclusion or exclusion of Hong Kong, Macao, Taiwan and offshore islands
+ Source-attributed geographic representations, coordinate reference systems and dates
+ Multilingual names and relationships to gazetteer records
+ Evidence needed to apply the designation to addresses, datasets and service coverage
- The People's Republic of China as a sovereign-state or government model
- Hong Kong, Macao and Taiwan as separately modelled places
- Chinese populations, citizenship, ethnicity and cultural identity
- The internal workings of provincial and local administrations
- Substantive laws, customs rules and commercial service policies
- China's complete physical geography and natural environments
Characteristics
- Interpretive context
- Conventional geographic, physical continental, administrative, statistical, legal or commercial usage The same name can select different extents depending on why it is used.
- Territorial inclusion decisions
- Named territory or island → included, excluded, partly included or unresolved, with source and date Explicit decisions prevent assumptions about Hong Kong, Macao, Taiwan and offshore islands.
- Extent representation
- Territory list, polygon, multipolygon, approximate envelope or textual definition A textual regional designation may not support precise spatial operations.
- Spatial reference and precision
- Declared coordinate reference system, coordinate convention, resolution and positional uncertainty Location matching is unreliable when coordinate conventions or boundary precision are unknown.
- Name and identifier correspondence
- Language-tagged names and verified gazetteer identifiers, with exact, broader, narrower or contextual match A similarly named gazetteer entry may represent China as a whole or a different regional interpretation.
- Boundary evidence status
- Source-supported, conflicting, outdated or unresolved; record publisher, claimant where applicable, and effective date An agent must distinguish evidence of an adopted boundary from evidence that all parties accept it.

Mainland meaning and names Establish what a speaker or publisher means by mainland China and how that meaning is expressed across languages.
The designation can be confused with China, the People's Republic of China or the physically continental landmass.
Contextual meaning
Separate conventional regional usage from literal continental and institution-specific meanings.
Meaning requires context
Record the interpretation used by the originating source before attaching a territorial extent.
- Does this source use mainland China as a conventional region, a physical landmass or an institution-defined area? definition
- What explicit wording distinguishes its use of mainland China from China or the People's Republic of China? boundary
Multilingual reference
Connect English and Chinese expressions to the intended sense without assuming exact equivalence.
Names preserve viewpoint
Treat mainland China, 中国大陆, 中國大陸 and context-dependent expressions such as 内地 or 內地 as names requiring source and usage context.
- Which original-language expression appears in the source, and from which regional or institutional context? provenance
- Does a candidate GeoNames or Wikidata record represent this same sense, or a broader or narrower place? definition
Territories and island inclusion Make the designation's most consequential inclusion decisions explicit.
Neither the word mainland nor a state boundary alone resolves the treatment of special administrative regions, Taiwan or islands.
Hong Kong, Macao and Taiwan
Record how the selected interpretation treats these places and why.
Separate scope from sovereignty
Preserve territorial inclusion decisions as attributed scope decisions, without treating them as universal conclusions about political status.
- Does the source explicitly exclude or include Hong Kong, Macao and Taiwan, and for what purpose? boundary
- Which publisher or authority supplied those decisions, and do its statements concern geographic coverage, jurisdiction or sovereignty? provenance
Continental and offshore land
Distinguish physical connection to the continent from membership in the named region.
Islands need explicit treatment
Use Hainan and source-relevant coastal or disputed islands to test whether the extent follows conventional usage, physical geography or an administrative selection.
- Is Hainan included despite its separation from the continental landmass, and what does that reveal about the definition? definition
- Which additional islands or island groups require explicit inclusion decisions rather than inference from a national outline? boundary
Mapped extent and boundary evidence Connect the interpreted region to spatial evidence that can support appropriate geographic operations.
A map labelled mainland China may encode a publisher's territorial claims, simplifications or coordinate conventions.
Geometry and coordinates
Document how the selected extent is represented and positioned.
Geometry must match meaning
Accept a spatial representation only when its territorial content and coordinate reference agree with the intended interpretation.
- What boundary dataset implements this definition, and how does it encode excluded territories and included islands? provenance
- What coordinate reference system, coordinate convention and resolution apply, and are they compatible with the locations being tested? measurement
Claims, dates and limits
Expose the authority, temporal validity and limitations of mapped boundaries.
Boundary is attributed evidence
Distinguish coastlines, administrative selections, effective control and territorial claims wherever they affect the adopted extent.
- Who published the boundary, what date does it represent, and whose claims or administrative practice does it encode? provenance
- Does the representation cover land only, inland waters or maritime areas, and where do conflicting interpretations remain? boundary
Mainland classification and use Determine which practical decisions the selected interpretation can support.
A geographic mainland label does not automatically establish statistical comparability, jurisdiction or commercial eligibility.
Location and dataset matching
Apply an explicit interpretation to addresses, coordinates and regional aggregates.
Classification retains scope
Return inclusion results with the chosen definition and preserve unresolved cases instead of forcing a binary decision.
- Is there enough address or coordinate evidence to classify this location under the selected mainland-China extent? measurement
- Before combining datasets labelled mainland China, do their treatment of Hong Kong, Macao, Taiwan and islands agree? boundary
Policy-dependent actions
Connect geographic classifications to separately evidenced rules for reporting, routing or service coverage.
Geography does not complete eligibility
Require the relevant policy's own mainland-China definition before using regional membership to decide an action.
- Which current policy governs the proposed delivery, service or reporting action, and how does it define mainland China? action
- What should the agent do when the policy's coverage differs from the selected geographic extent or leaves a location unresolved? action
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.
A model that cannot be lined up against existing standards, identifiers and practice cannot be adopted by anyone who already uses them.
Reported evidence
Findings from the breadth pass, kept separate from the structural claims.
Check these first
Recalled without web access and unsourced; every item is a lead to verify.

- Which of these failure modes and hazards hold for the sense of mainland China this model covers, and on what evidence? provenance
Regional variation
Recalled without web access and unsourced; every item is a lead to verify.
- In Hong Kong and Macao, mainland commonly distinguishes the rest of PRC-administered territory from the two special administrative regions.
- In Taiwan, mainland is used in cross-strait discourse; legal and political usages require their own definitions.
- In physical geography, mainland can mean the continental landmass, a narrower sense than the usual jurisdictional usage.
- Which of these regional variation hold for the sense of mainland China this model covers, and on what evidence? provenance
Neighbouring kinds and how to tell them apart
Recalled without web access and unsourced; every item is a lead to verify.
- People's Republic of China - A state whose administration includes Hong Kong and Macao; mainland China ordinarily excludes both.
- China - A broader name that can denote a state, historical region or cultural sphere; mainland China specifies a narrower contextual extent.
- Hong Kong - A special administrative region of the PRC ordinarily excluded from mainland China.
- Macao - A special administrative region of the PRC ordinarily excluded from mainland China.
- Taiwan - Administered separately from the PRC and excluded from ordinary mainland-China coverage; this distinction does not resolve competing sovereignty claims.
- Hainan - An island province ordinarily included in mainland China despite being physically separate from the continental landmass.
- Which of these neighbouring kinds and how to tell them apart hold for the sense of mainland China this model covers, and on what evidence? provenance
What the second pass must settle
- Which originating registry or gazetteer source establishes the intended sense of vr.tr.mainland-china, given that no definition is recorded?
- Which verified GeoNames and Wikidata identifiers match that sense rather than China or the People's Republic of China?
- Which authoritative or clearly attributed sources should govern Hong Kong, Macao, Taiwan, Hainan and other island inclusion for the registry's default interpretation?
- Which boundary dataset, date and coordinate reference best implement that interpretation, and how should conflicting territorial claims be represented?
- Should the default extent cover land only, and which contextual interpretations require separate treatment of inland or maritime waters?
