Protests from South Korea, Japan as North Korea conducts second missile test in a week

North Korea appeared to test fire a ballistic missile on Tuesday for the second time in less than a week, drawing condemnation from South Korea and Japan where officials said the repeated launches risked destabilising the region.

The suspected ballistic missile launch was detected around 7:27am (2227 GMT) from an inland area of North Korea toward the ocean off its east coast, South Korea's Joint Chiefs of Staff (JCS) said in a statement.

South Korea's National Security Council held an emergency meeting and expressed "strong regret" that the missile test came at a time when regional stability is extremely important.

"Members of the NSC urged North Korea to swiftly respond to the international community's expectations for peace and stability on the Korean peninsula, and agree to resume dialogue and cooperation," the presidential Blue House said in a statement.

Coming after nuclear-armed North Korea claimed to have tested a hypersonic missile on Wednesday, the launch underscored leader Kim Jong Un's New Year's vow to bolster the military at a time when talks with South Korea and the United States have stalled.

Japan's defence ministry said that if the projectile followed a normal trajectory for ballistic missiles it would have flown less than 700 km, similar to recent tests of short-range ballistic missiles by North Korea.

The South Korean military said it was cooperating with its US allies and closely monitoring the situation in preparation for additional launches.

Leif-Eric Easley, a professor of international studies at Seoul's Ewha University said North Korea is attempting to use repeated tests to normalise its missile capabilities, portraying itself as a country engaged in incremental improvements for self-defence,.

"At the same time, Pyongyang is challenging international sanctions, testing what it can get away with while the United Nations Security Council remains divided," he said.

'SIGNIFICANT THREAT'

Japanese Prime Minister Fumio Kishida noted the United Nations had just finished holding discussions on how to respond to last week's launch.

"That North Korea continues to launch missiles is extremely regrettable," he told reporters.

Tuesday's apparent launch came a day after the United States mission to the United Nations, joined by France, Ireland, Japan, the United Kingdom and Albania, issued a joint statement condemning last week's test.

"These actions increase the risk of miscalculation and escalation and pose a significant threat to regional stability," US Ambassador Linda Thomas-Greenfield said in the statement on Monday. Such tests not only improve the North's capabilities, but expands what it can offer illicit arms clients and dealers around the world, she added.

"(North Korea) makes these military investments at the expense of the well-being of the North Korean people," she said.

UN Security Council resolutions ban all ballistic missile and nuclear tests by North Korea, and have imposed sanctions over the programmes.

"Today's test might be intended to send a message to the South after authorities here said the earlier test was a failure and did not involve a hypersonic missile," Kim Dong-yup, a former South Korea Navy officer who now teaches at Seoul's Kyungnam University.
