U.S. National Security Adviser Jake Sullivan spoke by phone with South Korea National Security Adviser Kim Sung-han to discuss North Korea's launch of three ballistic missiles, the White House said late on Tuesday.
"They both condemned the DPRK's destabilizing ballistic missile tests and committed to continue building on their close coordination. Mr. Sullivan also reaffirmed the United States' steadfast commitment to the defense of the ROK," the White House said in a statement.
