President Bush is to begin his day in China by attending a Church service in Beijing before holding talks in which he is expected to stress religious freedoms, human rights and trade. After the Sunday morning church service, Mr. Bush will attend a welcoming ceremony at the Great Hall of the People before meeting with Chinese President Hu Jintao. The two presidents are expected to discuss religious freedom in China along with North Korea's nuclear programs and trade issues. In his weekly radio address on Saturday to the American people, the president called on China to protect intellectual property rights and to create a flexible exchange system for its currency. Later in the day, Mr. Bush will go bicycle riding with Chinese athletes training for the Olympic Games.
