Prez Xi vows to push ahead with China's "reform and opening up"

President Xi Jinping vowed Tuesday to push ahead with China's "reform and opening up" but warned that no one can "dictate" what it does, as the Communist Party celebrated the policy's 40th anniversary.

"No one is in a position to dictate to the Chinese people what should or should not be done," Xi said as China faces a stern challenge from the United States over trade and diplomacy.
