china has 10 distinct synonyms spread across 3 of its 4 senses. Each sense below keeps its own list, because a synonym belongs to a meaning and not to a word: swapping one sense's substitute into another sense's sentence is how a thesaurus makes writing worse. WordNet records no antonym for it — antonymy is a relation between word forms rather than concepts, so it is deliberately sparse.
Counts are distinct word forms across every sense. A synonym that appears under three senses is counted once here and shown three times below, under each sense it belongs to.
a communist nation that covers a vast territory in eastern Asia; the most populous country in the world
high quality porcelain originally made only in China
a government on the island of Taiwan established in 1949 by Chiang Kai-shek after the conquest of mainland China by the Communists led by Mao Zedong
