S. Korean president said that the North's steps towards denuclearization should be acknowledged.

The U.S. criticized Seoul after S. Korean foreign minister said N. Korea sanctions were under review.

The North Korean leader is ready to allow international inspectors into his nuclear and missile testing sites.

In a “leap forward” N. Korea’s Kim Jong-un has agreed to permanently shut down a key facility for testing and launching missiles if the U.S. takes “reciprocal measures,” said the South’s President Moon Jae-in.

U.S. President Donald Trump added that he saw no reason to resume joint military drills with S. Korea.

In an apparent departure from its commitment to mothball its nuclear and missile programs, N. Korea might be building new ballistic projectiles as claimed by U.S. officials citing images by America’s spy satellites.

The talks will also include the issue of recovering the remains of U.S. troops missing from the Korean War.

The media highlighted Trump’s surprise concession of halting joint U.S.-South Korea military exercises.

The two sides would join the negotiation tables expecting “quick, deliverable concessions.”

The details of the letter are not known but the gesture fuels optimism that the June 12 summit may go ahead.
