US President Donald Trump embarked on an 11-day trip to Asia during which he will visit Japan, South Korea, China, Vietnam and the Philippines.
It will be the longest tour of Asia by a US president in 25 years.
The trip comes at a time of heightened tensions with North Korea over its nuclear programme and missile tests.
BBC reported that Trump is expected to show a united front with South Korea and Japan while pressing China to take a stronger line with Pyongyang.
President Trump flew first to the US state of Hawaii where he visited the USS Arizona Memorial at Pearl Harbor – the scene of the 1941 Japanese attack that drew the US into World War Two.
From Hawaii, he and First Lady Melania Trump will head to Japan and then on to South Korea.
