The National People's Congress in Beijing adopts the Anti-Secession Law on March 14, 2005, aimed at "opposing and checking Taiwan's secession from China." The law reaffirms the "One China principle" as the basis for peaceful reunification, lays out measures to promote greater cross-Strait exchange, and outlines subjects for negotiation. However, "in the event that the 'Taiwan independence' secessionist forces should act under any name or by any means to cause the fact of Taiwan's secession from China, or that major incidents entailing Taiwan's secession from China should occur, or that possibilities for a peaceful reunification should be completely exhausted," China "shall employ non-peaceful means and other necessary measures." The law is met with almost unanimous opposition in Taiwan, prompting a popular protest two weeks later. The Bush administration calls the law "unnecessary" and "unfortunate," while Congress passes a resolution expressing its "grave concern."
