North Korea fired missiles into the sea off its east coast for the fourth time in less than two weeks, South Korea said today, as Pyongyang warned that hostile moves against it "have reached the danger line."
The North, criticising the US-South Korean drills and their use of high-tech weapons, has fired a series of missiles and rockets since its leader Kim Jong Un and US President Donald Trump agreed at a June 30 meeting to revive stalled denuclearisation talks.
North Korea said it is committed to diplomacy and will wait until the end of the year for the United States to soften its policy of sanctions and political pressure over Pyongyang's nuclear weapons and ballistic missile programmes.
But if Washington and Seoul disregard North Korea's repeated warnings, "we will make them pay (a) heavy price," a North Korean foreign ministry spokesman said in a statement released through state news agency KCNA.
Trump has played down the tests by saying they did not break any agreement he had with Kim but the talks have yet to resume. Analysts believe the tests are designed both to improve North Korean military capabilities and to pressure Washington to offer more concessions.
"Part of what's happening now is that North Korea is expressing frustrations with a general lack of progress on inter-Korean agenda while increasing leverage in US-North Korea negotiations by demonstrating how its programmes could and will continue to advance," said Jenny Town, managing editor at 38 North, a website that tracks North Korea.
Multiple missile launches
South Korea's joint chiefs of staff (JCS) said what appeared to be two short-range ballistic missiles were fired from near Kwail on North Korea's west coast, about 125km southwest of Pyongyang, in South Hwanghae province early today. They were the fourth set of launches since July 25.
The missiles flew about 450km and reached an altitude of 37 km, the JCS said. US and South Korean intelligence agencies deemed they had similar flight characteristics to the short-range ballistic missiles launched by North Korea on July 25, it said.
Kim Dong-yub, a military expert at South Korea's Kyungnam University, said the latest launch area was significant because the flight path of 450km meant that all of South Korea was in the range of such missiles.
"It becomes difficult to detect the origin of the launch in advance because it is capable of launching a missile from most anywhere in North Korea, targeting all of South Korea," he said.
South Korea's defence ministry said the missile launch went against the spirit of easing tension on the Korean peninsula.
A United Nations report said on Monday Pyongyang has continued to enhance its nuclear and missile programmes and used cyberattacks to take in US$2 billion to fund the development.
The missile tests represent military advances, as well as help Kim strengthen his bargaining power with the United States, said Van Jackson, a former Pentagon official focused on Korea.
"Kim believes he doesn't need to compromise to get what he wants, doesn't need to conduct serious negotiations at the working level because he has recourse to Trump, and doesn't need to restrain any of his missile testing or actions abroad as long as he doesn't test an intercontinental ballistic missile," Jackson said.
‘Do us harm’
The launches on July 25 were the first since Trump and Kim met at the heavily armed Demilitarized Zone that separates the two Koreas on June 30. What was agreed at that meeting is now under scrutiny.
The North Korean foreign ministry spokesman said the North remained committed to resolving issues through dialogue, but that the United States and South Korea's joint military drills violate a pledge made by Trump to Kim.
Pyongyang "will be compelled to seek a new road as we have already indicated" if South Korea and the United States continue with hostile military moves, he said.
The arrival of new, US-made F-35A stealth fighters in South Korea, the visit of a US nuclear-powered submarine to a South Korean port, and US tests of ballistic missiles are among the steps that forced North Korea to continue its own weapons development, the spokesman said.
"The US and South Korean authorities remain outwardly talkative about dialogue," he said. "But when they sit back, they sharpen a sword to do us harm."
South Korean media reported that US-South Korea joint military exercises had started on Monday. A senior South Korean official said previously the drills would mainly involve computer simulations.
A JCS spokesman told a regular news briefing on Monday the allies were preparing for a joint exercise in the second half of the year but would not confirm the name of the drill or whether it had already started.
The testing of short-range missiles by North Korea is banned by a 2006 United Nations Security Council resolution demanding that North Korea suspend all activities related to its ballistic missile programme.
Japan's defence ministry said it did not see any imminent threat to Japanese security from the latest projectile launch by North Korea.
