In a rare defection from China, a senior officer of the People's Liberation Army has taken refuge in the United States (as of December). He is said to know a lot about China's strategic plans regarding the United States and Taiwan. Beijing takes defections seriously but this case apparently has NOT disrupted U.S.-China relations too much. Both sides were aware of it this week as President Bush and his aides met with Chinese Vice Premier Qian Qichen. Those talks were regarded as successful.
