U.S. President Barack Obama yawns as he sits between Japan's Prime Minister Yoshihiko Noda, right, and Chinese Premier Wen Jiabao during the plenary session of the 21st ASEAN (Association of Southeast Asian Nations) and East Asia summits in Phnom Penh, Cambodia on November 20, 2012. In his first meeting with a Chinese leader since his re-election, Obama said on Tuesday Washington and its chief economic rival must work together to "establish clear rules of the road" for trade and investment.

President Barack Obama, who was in Cambodia for a summit of Asian leaders, spoke on the phone with Israeli and Egyptian leaders until 2:30 a.m. Tuesday local time, NBC News reports, to try to find a way to end the deadly Gaza crisis.

Later Tuesday, Obama met separately with Chinese and Japanese leaders before taking his seat at the East Asia Summit, at which point his busy schedule appeared to catch up with him.
