President Donald Trump will host a lunch meeting with Prime Minister Shinzo Abe and South Korean President Moon Jae-in next Thursday in New York, a senior White House official has said.

Meeting on the sidelines of the U.N. General Assembly, the three leaders will focus on the rising threat posed by North Korea, including a ballistic missile launch over Hokkaido on Friday and Pyongyang's sixth and most powerful nuclear test on Sept. 3, Trump's national security adviser, H.R. McMaster, told reporters Friday.

"As Kim Jong Un's most recent missile launch demonstrates, North Korea remains one of the world's most urgent and dangerous security problems," McMaster said, in reference to the North's leader.
