The warning from Beijing, which considers Taiwan its territory, came after days of unprecedented Chinese military drills around the island sparked by US House Speaker Nancy Pelosi's trip.
Pelosi last week became the highest-ranking US official to visit Taiwan in decades despite stark threats from China, which tries to keep Taipei isolated on the world stage.
China's Taiwan Affairs Office on Wednesday issued a white paper laying out how it intends to claim the island through a range of economic incentives and military pressure.
