WASHINGTON -- As U.S. President George W. Bush travels to East Asia to hold summit meetings with the leaders of Japan, South Korea and China, he does so against a backdrop of dramatically improved U.S.-Chinese relations. Tensions between the two countries have eased considerably since the initial period of the Bush presidency.

Various commentators around the world have noted Beijing's surprisingly mild reaction to revelations that electronic listening devices had been planted on President Jiang Zemin's American-built airplane. Even though Chinese officials implied that the bugging was a U.S. intelligence operation, there were no official charges of spying, nor did the state-controlled media launch an anti-U.S. propaganda campaign. Indeed, the media virtually ignored the incident.

That reaction was in sharp contrast to the shrill statements from Chinese leaders and the massive propaganda offensive that followed the collision between a U.S. spy plane and a Chinese fighter jet in April 2001. The reasons for that difference suggest a number of things about China's internal politics and foreign policy.
