North Korea will want President Trump to sign a peace treaty after the two leaders meet for a historic summit, a longtime goal of the reclusive regime, according to a report on Monday.

President Kim Jong Un is expected to introduce the possibility of inking a peace treaty, along with starting diplomatic relations and ending his nuclear weapons program during the meeting with Trump, Bloomberg reported, citing South Korea’s Dong-A-Ilbo newspaper.

North Korea has been wanting to sign a peace accord with the United States to end the more than 60-year-old ceasefire between the two countries and to guarantee its safety, Koh Yu-hwan, a teacher of North Korean studies at Dongguk University in Seoul, told Bloomberg.

“There were agreements between the U.S. and North Korea to open up discussion on a peace treaty, but they never materialized,” Koh said, adding the conditions were key to the process. “The U.S. wants a peace treaty at the end of the denuclearization process, while for the North, it’s the precondition for its denuclearization.”

Getting a peace treaty would force a discussion about the US military’s role in South Korea, Koh said.

The United States routinely conducts military exercises with South Korean forces, operations that Kim’s regime views as rehearsals for an invasion.

Trump announced the summit suddenly last Thursday after months of name-calling and saber-rattling between the two countries after North Korea began test-firing ballistic missiles and working on perfecting a nuclear device.

The meeting, the first time in history that an American president will sit down with a North Korea leader, could come as soon as May.
