Seoul, Jan 30 : South Korean President Moon Jae-in said on Sunday that North Korea has inched closer to scrapping its self-imposed moratorium on testing intercontinental ballistic missiles (ICBMs) shortly after the latter fired an intermediate-range ballistic missile. Moon made the remarks while presiding over a plenary meeting of the National Security Council (NSC) for the first time in about a year, an indication of how seriously he takes the launch of what is believed to be the longest-range missile the North has fired in recent years, reports Yonhap News Agency. South Korea's Joint Chiefs of Staff said the North's missile flew about 800 km at a top altitude of 2,000 km. The flight data indicated that North Korea has test-launched its biggest ballistic missile since 2017. The launch also marked the North's seventh show of force this month alone. "North Korea has kept the moratorium on nuclear tests and ICBM launches so far while expressing a willingness for dialogue. But if it did fire an intermediate-range ballistic missile, we can consider they have moved closer to scrapping the moratorium," Moon was quoted as saying during the meeting. The President called for North Korea to stop creating tension and respond to international calls for dialogue. He said the North's latest launch was "a challenge for denuclearization of the Korean Peninsula, peace and stability on the Korean Peninsula, and diplomatic efforts by the international community, as well as an act that violates the UN Security Council resolution. During the meeting, Moon said North Korea may repeat a situation shown in 2017, when Pyongyang heightened tensions by launching intermediate-range and intercontinental ballistic missiles. After the plenary meeting ended, National Security Adviser Suh Hoon held a separate NSC meeting and condemned the North's launch of an intermediate-range ballistic missile. North Korea has maintained a self-imposed moratorium on nuclear and ICBM testing since late 2017. Since the start of this year, North Korea has been ratcheting up tensions with a series of missile launches as the US stepped up sanctions pressure amid stalled denuclearization talks between the two countries. On January 20, Pyongyang made a thinly veiled threat to lift its years-long moratorium on nuclear and long-range missile tests, sparking speculation it would engage in more provocative actions down the road. The North launched the largest monthly number of projectiles in January since North Korean leader Kim Jong-un took power in late 2011. It conducted six projectile launches in both March and July 2014. /IANS
