Any move by the United States to place new ground-launched, intermediate-range missiles in South Korea could spark a "new Cold War" and an escalating arms race in the region, North Korean state media said on Wednesday.

U.S. Defense Secretary Mark Esper this month said he was in favor of placing ground-launched, intermediate-range missiles in Asia, a day after the United States withdrew from the Intermediate Nuclear Forces (INF) treaty with Russia.

"The U.S. pointed out that it is now examining a plan for deploying ground-to-ground medium-range missiles in the Asian region and South Korea has been singled out as a place for the deployment," North Korea's state news agency KCNA said.
