China appointed the liberal mayor of Shanghai and the nation's economic planning chief as new vice premiers Monday, in what analysts say represents a marginal sign of Chinese leaders' continued commitment to economic reform.

The appointments were approved by the current session of the National People's Congress, the country's rubber-stamp parliament, but reflect choices made by Communist Party leaders in advance.Foreign Minister Qian Qichen also was named to the post of state councilor, joining a panel of senior officials who act as high-level advisers to the government.
