Vice President Biden will meet separately with the leaders of Japan, China and South Korea on a week-long trip to Asia starting Sunday during which he will convey the Obama administration's concerns over China's recent provocations in the East China Sea, officials said Wednesday.

The vice president's trip comes as the administration hopes to quell doubts among allies and rivals over the U.S. commitment to the Asia-Pacific region. President Obama canceled his trip to two summits in southeast Asia last month during the partial government shutdown.

Officials said Biden will have high-level, wide-ranging talks with Chinese President Xi Jinping during his stop in Beijing, but they acknowledged that the vice president is likely to raise objections to China's claim last weekend of control of an "air defense identification zone" over disputed waters between itself and U.S.-ally Japan.
