BUENOS AIRES: Chinese President Xi Jinping (shee jihn-peeng) will meet with President Barack Obama in Washington next week on the sidelines of a nuclear security summit.

Obama will host Xi on March 31. The White House says they'll discuss cooperation as well as areas of disagreement between the US and China.

Dozens of world leaders are heading to Washington for the summit, which focuses on preventing terrorists from obtaining nuclear weapons.

Obama has sought China's cooperation on punishing North Korea for its nuclear weapons program and on climate change. The two countries remain at odds on maritime disputes, cybersecurity and other issues.

Obama and Xi have met frequently in recent years in the US, China and in third countries.

The White House announced the meeting while Obama was traveling in Argentina.
