U.S. President Donald Trump said on Saturday that Kim Jong Un told him he was ready to resume talks on North Korea’s nuclear and missile programs and would stop missile testing as soon as U.S.-South Korea military exercises end.

Axar.az reports citing Reuters that Trump and Kim have met twice since their first summit in Singapore last year, but little progress has been on Washington’s aim of getting the North Korean leader to give up his weapons.

“I look forward to seeing Kim Jong Un in the not too distant future!” Trump said on Twitter.

North Korea fired what appeared to be two short-range missiles on Saturday, South Korea said, in a “show of force” against the exercises.

Kim Dong-yup, a former naval officer who teaches at Seoul’s Kyungnam University, said the weapons could be related to the completion of North Korea’s new rocket artillery system that required multiple launches of the same kind.

Japan’s ministry of defence said the projectiles did not pose an immediate security threat.
