On Sunday, North Korea said it detonated a hydrogen bomb designed for a long-range missile and called its sixth and most powerful nuclear test a "perfect success", sparking world condemnation and promises of tougher US sanctions.
President Trump's call to Xi Jinping is part of his efforts to reach out to global leaders on the issue of North Korean threat.
This would be the first phone call between the two leaders after North Korea carried out another nuclear test a few days ago and has threatened to equip its ballistic missile with nuclear weapons. "In the morning, President Donald Trump will speak with President Xi Jinping of China," the White House said.
Over the past few days, he has spoken multiple times with Japanese Prime Minister Shinzo Abe.He also spoke over phone with German Chancellor Angela Merkel and South Korea President Moon Jae-In.
Speaking at the Center for Strategic and International Studies, Congressman Stephanie Murphy, said North Korea's nuclear test are a profoundly dangerous, defiant, and destabilising event.
"As expected, the test has generated verbal condemnation from the international community, including China and Russia. But it is too early to say whether these strong words will be followed by strong actions and, if so, what those actions will entail-and whether they will make any difference in altering North Korea's strategic calculus," he said.
