WASHINGTON: President Barack Obama is thanking Chinese President Xi Jinping (shee jihn-peeng) for China's role in securing the nuclear deal with Iran.

The White House says Obama and Jinping spoke Monday, the same day the UN Security Council unanimously endorsed the deal.

China is a permanent member of the Security Council and was part of the group of five Security Council members plus the EU that negotiated the deal with Iran.

The Security Council resolution also approved a provision to automatically reinstate sanctions if Iran cheats. The US had been concerned China or Russia might be reluctant to those "snap back" sanctions.

The White House says Obama and Xi agreed cooperation between the US and China is critical to the deal's implementation.

Xi plans to visit the White House in September.
