North Korea will be on the top of the agenda of United States President Donald Trump’s 10-day Asia trip that begins on Saturday, Reuters reported.

The president is going to tell leaders in the five nations he is visiting that the international community was running out of time on North Korea’s nuclear crisis and that it needs to do more. “The president recognises that we are running out of time [to deal with North Korea] and will ask all nations to do more,” White House National Security Adviser HR McMaster said.

Trump is also mulling over a move to designate North Korea a sponsor of terrorism, AP reported. In a show of strength, two B-1B bombers flew near North Korea on Thursday, alongside Japanese and South Korean jet fighters, provoking anger from Pyongyang, DPA reported. The US Treasury on Thursday also blacklisted a Chinese bank it accused of laundering money for North Korean concerns.

Trump’s visit to Japan, South Korea, China, Vietnam and the Philippines will be the longest Asia tour by an American president in more than 25 years.
