U.S. Secretary of State John Kerry, now in Beijing, will urge China to do more to press North Korea to stop its controversial nuclear tests during his talks beginning shortly in the Chinese capital.

Kerry has meetings planned with Chinese Foreign Minister Wang Yi early Wednesday, and the two top diplomats will hold a news conference before they hold further talks at a working lunch, U.S. officials said.

Earlier this month, Pyongyang conducted what it said was a successful test of a hydrogen bomb -- a move that drew international condemnation.

China is an economic lifeline for North Korea. A focal point for Kerry will be urging Beijing to use its leverage to try to convince Pyongyang to stop such tests, which are considered provocative by world powers.
