North Korea wants international sanctions banning its metal exports and imports of refined fuel and other necessities lifted before it restarts denuclearization talks with the United States, South Korean lawmakers said on Tuesday.

The United States, Japan and South Korea have also imposed their own sanctions on North Korea.

North Korea has not tested a nuclear weapon or its longest-range intercontinental ballistic missiles (ICBMs) since 2017, ahead of a historic meeting in Singapore between Kim Jong Un and U.S. President Donald Trump in 2018.

Trump had two subsequent meetings with Kim but without progress on getting the North to give up its nuclear and missile programs in exchange for sanctions relief.
