WASHINGTON: Indonesia's leader and President Barack Obama are set to hold talks Monday expected to address the threat posed by Islamic extremism and tensions in the South China Sea.

President Joko Widodo swept to power last year on a wave of popular support.

His first Washington visit as president is a chance to build rapport with Obama, who spent part of his childhood in Indonesia, and to attract investment in Southeast Asia's biggest economy.

Indonesia balances its relations between the US and China but is concerned about China's expansive maritime claims and is seeking US help to develop its coast guard.

The two leaders are expected to discuss climate change. Indonesia is major source of greenhouse gas emissions.
