The White House said that US President Donald Trump and Japan’s prime minister Shinzo Abe have agreed during a phone call to closely consult after the summit in Singapore.

The White House stated on Monday that US President Donald Trump and Japan’s Prime Minister Shinzo Abe during their telephone conversation have discussed recent developments regarding the summit with North Korea and agreed to consult closely following the meeting.

Also, the White House said in a press release that US President Donald Trump and South Korean President Moon Jae-in have discussed by phone prior to the Singapore summit maintaining close coordination on North Korea.

"Trump spoke yesterday with President of South Korea Moon Jae-in to discuss recent developments ahead of the summit with North Korea," the release said.

"The two leaders vowed to continue their close coordination following Trump’s meeting with North Korean leader Kim Jong Un in Singapore."

US President Donald Trump and North Korean leader Kim Jong-un are holding their first ever meeting in the hope of finding a peaceful solution to the nuclear crisis on the Korean Peninsula.

The United States, which has substantial presence in South Korea, was on a war footing with North Korea over Pyongyang’s nuclear and missile programs.

The development resurrected hopes that Trump and Kim could try to find a solution to the crisis on the Korean Peninsula that has escalated over the past year.
