SEOUL, SOUTH KOREA - Kim Jong Un slammed hostile forces that imposed sanctions on his country, North Korean state media reported Thursday, just hours before a crucial South Korea-U.S. summit in Washington.

Kim vowed to continue socialist economic reforms so as to deal a telling blow to the hostile forces who go with bloodshot eyes miscalculating that sanctions can bring the DPRK to its knees, the official Korean Central News Agency reported, using the countrys official acronym.

Later Thursday, South Korean President Moon Jae-in will visit the White House, where he is expected to push U.S. President Donald Trump to ease sanctions on North Korea in a bid to revive nuclear talks with Pyongyang.

The negotiations have been stalled since a February Trump-Kim meeting in Hanoi ended without a deal, in large part because of a disagreement over the pace of sanctions relief.

Bigger announcement coming?

North Korean officials have said Kim will soon decide whether to quit the U.S. talks and restart nuclear and missile tests.

That announcement could come this week during a session of North Koreas rubber-stamp parliament. Pyongyang often uses such meetings to make major policy announcements.

So far, Kim has refrained from making any especially fiery statements, suggesting he may wait for the outcome of the U.S.-South Korea summit.

Trump remains publicly optimistic about the talks, stressing that his close relationship with Kim may ultimately result in a nuclear agreement.

Stalled talks

But behind the scenes, U.S. negotiators do not appear to be making progress.

The Washington Post reported late Wednesday the United States and North Korea have not held working level talks since the collapse of the Hanoi summit, and that North Korean officials have not responded to requests for further dialogue.

An Asia policy specialist briefed by the White House confirmed to VOA that U.S. officials have tried to contact their North Korean counterparts through the so-called New York channel, the Norths United Nations mission in New York, but have not received replies.

North Korea may also be preparing for a provocative military parade, according to commercial satellite images analyzed by the Center for Strategic and International Studies Beyond Parallel program.

The group says images from earlier this week show military vehicles gathered at a parade training facility in Pyongyang.

Although (the images are) not conclusive, North Korea may be preparing for a parade to honor Kim Il Sungs birthday (April 15) or Korean Peoples Army (KPA) Foundation Day (April 25), said Beyond Parallel.

Trump still hopeful

Despite the faltering talks, U.S. Secretary of State Mike Pompeo has said he is hopeful Trump and Kim can soon meet for a third summit to break the deadlock.

Trump and Kim first met in Singapore in June 2018. The two leaders agreed to work toward the denuclearization of the Korean Peninsula, but U.S. officials later conceded the two sides have not agreed on what that means.

North Korea wants the sanctions relief to come in phases, as it makes concessions on its nuclear program. But U.S. officials have said they will not lift sanctions until North Korea completely gives up its nuclear weapons.

South Koreas Moon prefers Trump take the phased sanctions approach. He is also trying to get U.S. support to resume inter-Korean projects, such as the Kaesong Industrial Complex or tours of North Koreas Mount Kumgang.

Moon has reached the limit on inter-Korean projects he can put in place without sanctions relief, or without causing tensions in the U.S. South Korea alliance, says Chung Min Lee, a senior fellow at the Carnegie Endowment for International Peace.

Permanent peace is only possible if progress toward denuclearization can be made, Lee said. So Moon has a lot riding on this meeting.

Moon is set to meet separately with Pompeo and Vice President Mike Pence Thursday before meeting with Trump.

Ahead of the summit, an official with South Koreas presidential office said Seoul hopes to use the meeting to quickly revive momentum in the nuclear talks.
