What country most vehemently disputes Beijing's contention that the only China is the People's Republic of China?

• A. Japan
• B. Taiwan
• C. Mongolia
• D. South Korea

Answer: (B)

The key idea is sovereignty and how different entities claim representation of China. Beijing argues there is only one China and that Taiwan is part of it, under the government of the People’s Republic of China. The country that most strongly challenges that view is Taiwan, which governs itself as the Republic of China and maintains that it is a separate, sovereign state with its own government, constitution, and international presence. Taiwan has long resisted Beijing’s claim and seeks to maintain distinct status in many areas, even as international recognition has become constrained by PRC diplomacy. The other countries listed do not contest the One China principle with the same ongoing, explicit claim to be a separate China, so they don’t fit as the strongest challenger in this context.
