U.S. President Barack Obama arrives in Cambodia Monday where he met with Cambodian Prime Minister Hun Sen.
The trip comes less than two weeks after his re-election, and is aimed at showing how serious Obama is about shifting the U.S. strategic focus eastwards. The so-called "Asia pivot" is also meant to counter China's rising influence.
Obama also met with the 10 leaders of the Association of Southeast Asian Nations Monday.
Obama is expected to raise the issue of the territorial dispute in the South China Sea at the meeting.
ASEAN showed rare unity Sunday saying that they had agreed not to "internationalize" their disputes over rival claims to the potentially oil-and-gas rich sea.
