Singapore: South Korea's Defense Minister Jeong Kyeong-doo is fending off calls to step up pressure on North Korea after it test-fired missiles last month.
Jeong told an annual security conference in Singapore Saturday that the tests are being investigated and a conclusion is within reach.
North Korea itself has defended the launches, saying it was exercising its right to self-defense.
The US and Japan say North Korea tested short-range ballistic missiles on May 4 and 9, ending a pause that began in late 2017. Both countries called it a violation of UN Security Council resolutions.
Jeong says Pyongyang has shown it intends to work toward peace and urged the international community to "assure North Korea that the decision to denuclearize is indeed the right decision."
