North Korea launched a fresh round of ballistic missiles into the sea early Tuesday and warned it could take a “new road” in response to U.S.-South Korean military exercises that began this week.

The North fired two short-range ballistic missiles from South Hwanghae Province in the western part of the country, South Korea’s Joint Chiefs of Staff said in a statement. The missiles traveled about 450 kilometers and reached a height of about 37 kilometers, it added.

U.S. and South Korean intelligence officials say the missiles appear to be similar to the short-range ballistic missiles launched by North Korea on July 25, the statement said.
 
North Korea has conducted four rounds of short-range ballistic missile launches in about the past two weeks, as it expresses its anger at U.S.-South Korean military exercises.
 
‘Flagrant violation’

Minutes before the latest test, North Korea’s foreign ministry released a statement slamming the joint drills as a “flagrant violation” of its recent agreements with Washington and Seoul.

“We have already warned several times that the joint military exercises would block progress in the DPRK-U.S. relations and the inter-Korean relations and bring us into reconsideration of our earlier major steps,” said a North Korean foreign ministry spokesperson quoted by the official Korean Central News Agency (KCNA).

The U.S. and South Korea moved ahead with the joint exercises, which started Monday, even while calling on North Korea to engage in working-level nuclear talks. The U.S. and South Korea say the drills are defensive in nature, while North Korea sees them as preparation to invade.

“The U.S. and South Korean authorities remain outwardly talkative about dialogue. But when they sit back, they sharpen a sword to do us harm,” the KCNA statement said, adding Pyongyang may “be compelled to seek a new road as we have already indicated.”

South Korea’s presidential Blue House convened an emergency meeting to discuss the launch, a spokesperson said.

U.S. President Donald Trump, who wants to continue talks with North Korea, has said he has “no problem” with North Korea’s recent missile launches, since they are short-range.

In a series of tweets last week, Trump said the missile tests “are not a violation of our signed Singapore agreement, nor was there discussion of short-range missiles when we shook hands.”

“There may be a United Nations violation, but Chairman Kim (Jong Un) does not want to disappoint me with a violation of trust,” Trump said. “There is far too much for North Korea to gain.”

Working-level talks
 
Trump has met North Korean leader Kim three times since last June — in Singapore, Vietnam and at the demilitarized zone separating the two Koreas.

At the DMZ meeting in late June, both sides agreed to soon hold working-level talks. But North Korea has not agreed to set a date to begin those talks.

In the KCNA statement Tuesday, the North held out the possibility of more dialogue.

“We remain unchanged in our stand to resolve the issues through dialogue. But the dynamics of dialogue will be more invisible as long as the hostile military moves continue,” the KCNA statement said.

“A constructive dialogue cannot be expected at a time when a simulated war practice targeted at the dialogue partner is being conducted, and there is no need to have a fruitless and exhausting dialogue with those who do not have a sense of communication,” it continued.

U.S. Secretary of State Mike Pompeo had hoped to meet his North Korean counterparts at a regional summit last week in Bangkok, Thailand. But North Korea did not send any officials to the meeting.

“I wish they’d have come here,” Pompeo told reporters before heading home from Thailand. “I think it would have given us an opportunity to have another set of conversations, and I hope it won’t be too long before I have a chance to do that.”

Increasing actions

North Korea has slowly been increasing its threats and provocations — a strategy analysts say is designed to increase pressure on Washington and Seoul without completely derailing the talks.

“As long as Trump has good rapport with Kim Jong Un, I’m not too concerned,” said David Kim, a North Korea specialist at the Stimson Center.

But he said the North’s latest provocations will likely further delay working-level talks, which U.S. officials had expected to start in mid-July.

“I don’t expect much traction as long as the drills are continuing,” he said. “So it may be awhile until we see lower-level talks resume.”

With talks stalled yet again, some U.S. officials are hinting that a fourth Trump-Kim summit may be in the works. Asked about that possibility last week in Thailand, Pompeo said: “Stay tuned.”
