Coinbase CEO Brian Armstrong said the "remote-first" company has had to adjust some policies to combat cybercrime.

North Korea has cut off official communications with Seoul and Washington, while Kim Jong Un has expanded his nuclear program and test-fired missiles in defiance of United Nations Security Council sanctions.

North Korea has a secret military base near the Chinese border to hold ICBMs that pose a "potential nuclear threat" to the United States, a new report said.

WASHINGTON/SEOUL (Reuters) -When South Korean President Lee Jae Myung meets U.S. President Donald Trump next week for their first summit, he'll face calls to pay more for the upkeep of American troops on the peninsula with security issues expected to be among the top agenda items.

The intercontinental ballistic missiles likely to be housed at the military base “pose a potential nuclear threat to East Asia and the continental United States,” researchers said.

The meetings come after Seoul and Tokyo reached trade deals with Washington that spared them from the highest tariffs after pledging hundreds of billions in new U.S. investments.

North Korea has built a secret missile base that could be used to launch a nuclear strike against the United States, according to satellite research.

US President Donald Trump and South Korean President Lee Jae Myung are set to hold their first summit meeting in Washington on Monday. This follows last month’s trade deal, which reduced US tariffs on South Korea from a threatened 25% to 15%.

Since taking office in a snap election in June, the liberal Lee has taken steps to lower tensions with the nuclear-armed North, and the issue is one where he is expected to find common ground with Trump, who still boasts of his historic summits with North Korean leader Kim Jong Un.
