The U.S. and South Korea are indefinitely postponing joint military drills as an “act of goodwill” towards North Korea, U.S. Defense Secretary Mark Esper said Sunday.

Esper stressed the importance of defusing tensions in the region and establishing peace among neighboring countries while speaking to reporters after attending the ASEAN Defense Ministers’ Meeting in Thailand’s capital Bangkok.

“We have made this decision as an act of goodwill to contribute to an environment conducive to diplomacy and the advancement of peace,” he said.
