"The two leaders have exchanged views on recent North Korea’s reaction," the statement read.
According to the office, Moon and Trump have also agreed on close cooperation, aimed to successfully hold the US-North Korean summit in June.
Reacting the drills, on May 15 North Korea made a decision to cancel ministerial-level talks with Seoul. The next day, North Korean First Deputy Foreign Minister Kim Kye Gwan said North Korea might cancel the summit between Kim and Trump, scheduled for June 12 in Singapore, if Washington continues its anti-Pyongyang hostile policy.
New tensions in diplomatic relations with Pyongyang emerged just weeks after a historic meeting between leaders of North and South Korea on April 27. During the meeting, the sides signed the Declaration for Peace, Prosperity, and Unification on the Korean Peninsula. The document committed the two countries to a nuclear-free peninsula and talks to bring a formal end to the Korean War.
