China on Sunday voiced regret that the United States was blocking a UN Security Council statement on Israeli-Palestinian violence as it urged greater international efforts to stop the bloodshed.

"Regrettably, simply because of the obstruction of one country, the Security Council hasn't been able to speak with one voice," Foreign Minister Wang Yi, whose country holds the Council's rotating presidency, told a virtual session. "We call upon the United States to shoulder its due responsibilities."

The United States, the primary ally of Israel, delayed the Security Council session from last week and has shown little enthusiasm for a statement.

President Joe Biden's administration says it is working behind the scenes and that a Security Council statement could backfire.

In its public remarks, the Biden administration has steadfastly said that Israel is justified in self-defense in response to rocket fire by Hamas, even while urging de-escalation.

Wang urged an immediate ceasefire and called for the Security Council to take "strong actions," including reiterating support for a two-state solution.

He said that China, which has been expanding its role in the world, would welcome hosting talks between Israeli and Palestinian representatives.
