President Donald Trump meets with North Korean leader Kim Jong Un at the demilitarized zone separating the two Koreas, in Panmunjom, South Korea, June 30, 2019.

WASHINGTON — President Donald Trump took to Twitter on Friday to downplay a series of North Korean ballistic missile launches and defend its leader, Kim Jong Un.

"Kim Jong Un and North Korea tested 3 short range missiles over the last number of days. These missiles tests are not a violation of our signed Singapore agreement, nor was there discussion of short range missiles when we shook hands," Trump wrote, adding that Kim "does not want to disappoint me with a violation of trust."

"He will do the right thing because he is far too smart not to, and he does not want to disappoint his friend, President Trump!"

Trump's tweets came a day after North Korea launched two short-range ballistic missiles into the sea. The missiles did not appear to pose any immediate threat to the U.S. or its allies in the region, three U.S. defense officials told NBC News.

Earlier this week, North Korea fired two ballistic missiles from the Hodo Peninsula in South Hamgyong province on the country's east coast. The projectiles appeared to be a different type than previous launches, South Korea's national defense minister, Jeong Kyeong-doo, said, according to South Korean news agency Yonhap.

The Pentagon and the White House did not immediately respond to CNBC's requests for comment.

This week's tests come on the heels of an earlier test in July that marked the first provocation since Kim and Trump agreed in June to revive denuclearization talks. A summit between the two leaders in February failed to secure a deal.

North Korea, the only nation to have tested nuclear weapons this century, spent most of Trump's first year in office perfecting its nuclear arsenal. The newest member of the world's exclusive nuclear weapons club has stopped testing of its nukes for now as the U.S. and international community offer the possibility of relief from crippling economic sanctions.
