The plans are set for President Donald Trump to meet North Korean President Kim Jong-un in Singapore on June 12 for a historic meeting between the leaders of the two nations.

Trump announced the date and location of the summit via Twitter, saying that he and Kim “will both try to make it a very special moment for World Peace!”

Trump or Kim could still pull out of the bilateral summit, Trump has indicated numerous times in the lead-up to Thursday’s announcement.

The highly anticipated meeting between Kim Jong Un and myself will take place in Singapore on June 12th. We will both try to make it a very special moment for World Peace!

Discussions in Singapore between the two presidents will center on plans to systematically denuclearize the Korean peninsula and thaw diplomatic tensions that have simmered since an armistice agreement signed in 1953.

Trump’s announcement comes less than 12 hours after he greeted Secretary of State Mike Pompeo and three American citizens who were released from North Korean custody earlier this week.
