US President Barack Obama on Wednesday praised his country's cooperation with China on climate change and hotspot regional issues.

Obama made the remarks during an official meeting with Chinese Foreign Minister Wang Yi at the White House. Wang is on a US visit from Feb 23 to 25.

Asking Wang to convey his greetings to President Xi Jinping, Obama said the US-China relationship is of vital importance, while both countries should continue communication and coordination.

Obama said he looked forward to Xi's attendance at the fourth Nuclear Security Summit to be held in Washington in late March.

Wang extended Xi's greetings to Obama and said China expects to maintain high-level strategic communication with the US and strengthen cooperation on international and regional hotspot issues to face global challenges together.

China supports the US in holding the Nuclear Security Summit, he added.
