North Korea says it won't give Trump a summit for free

The statement on Monday by Foreign Ministry adviser Kim Kye Gwan is the latest call by North Korea for US concessions ahead of an end-of-year deadline set by Kim Jong Un for the Trump administration to offer mutually acceptable terms for a deal to salvage nuclear diplomacy.

Following a US decision over the weekend to call off joint military exercises with South Korea to create space for diplomacy with the North, Trump in a tweet urged Kim Jong Un to "act quickly, get the deal done" and hinted at another summit between them, saying "See you soon!" But Kim Kye Gwan reiterated his government's stance that Washington must discard what North Korea sees as "hostile" policies to keep the negotiations alive.

"Although (North Korea and the United States) held three summits and other meetings since June last year, there hasn't been much improvement in relations and the United States has been just trying to buy time to its favor," he said in a statement carried by the official Korean Central News Agency.

"We are no longer interested in such meetings that provide us no benefit." The statement came hours after KCNA reported that Kim Jong Un supervised a parachuting drill by military sharpshooters and vowed to build an "invincible army," displaying more defiance despite the decision by the US and South Korea to shelve their drills.

It was North Korea's second publicized military drill in three days. A report Saturday said Kim urged combat pilots to prepare against enemies "armed to the teeth" while attending a flight demonstration.

North Korea has been ramping up missile tests and other military demonstrations in recent months in an apparent pressure tactic over the talks.

Negotiations have faltered since a February summit between Kim and Trump in Vietnam which broke down after the US rejected North Korean demands for broad sanctions relief in exchange for a partial surrender of its nuclear capabilities.

Kim later issued his end-of-year deadline and has also said the North would seek a "new path" if the United States persists with sanctions and pressure.

Working-level talks last month in Sweden broke down over what the North Koreans described as the Americans' "old stance and attitude." North Korea last week said the United States has proposed a resumption of the stalled nuclear negotiations in December.

North Korean negotiator Kim Myong Gil didn't clearly say whether the North would accept the supposed US offer and said the country has no interest in talks if they are aimed at buying time without discussing solutions.

He said North Korea isn't willing to make a deal over "matters of secondary importance," such as possible US offers to formally declare an end to the 1950-53 Korean War, which was halted by a cease-fire, not a peace treaty, or establish a liaison office between the countries.
