Taiwan

After the US announced sales of over US$6 billion worth of advanced weapons to Taiwan, China lodged a protest and accused the US of violating "the principles set in the three joint communiques between China and the United States, especially the communique on the U.S. arms sales to Taiwan signed on Aug. 17, 1982". A Foreign Ministry spokesman declared that "nobody could stop the efforts to promote cross Strait exchanges and opening a new chapter of peace in cross Strait relations". If that is indeed the case, what's the big deal?
