BANGKOK -- U.S. President Donald Trump's national security adviser on Monday called on countries intimidated by Beijing in the South China Sea to seek arbitration, as Washington put pressure on China at one of Asia's largest diplomatic gatherings.
Robert O'Brien, who represented Trump during the ASEAN Summit and related meetings, also announced an initiative aimed at countering China's Belt and Road infrastructure program -- the latest move in the deepening rivalry between the U.S. and China in the region.
