The timing would mean Pyongyang tested the weapon the same day as a testfire of twin short-range projectiles, hours after Pyongyang signalled was open to resuming talks with Washington. South Korea said North Korea fired "short-range projectiles" into its eastern seas that flew about 330 kilometers (200 miles).
While analysts said North Korea conducts weapons tests for a range of purposes, including technical development and reassurance for the defence establishment, Tuesday's launches appeared to have been timed to send a message to Washington regarding what may happen if the United States does not come to North Korea with realistic proposals.
"It's possible that the missiles were fired from. a 600 mm super-large multiple rocket launcher, or a new missile system, given their flight from an inland area to the East Sea and their flight distances", the spokesman added.
Last month, North Korean Foreign Minister Ri Yong-ho called his USA counterpart, Mike Pompeo, "the diehard toxin of the US diplomacy" for suggesting that all sanctions on the North would remain in place until the North's denuclearization.More news: Public not welcome at Mugabe's private funeral

Trump's efforts to engage with North Korea almost fell apart altogether in February after he followed Bolton's advice at the second summit in Hanoi and handed Kim a piece of paper that called for the transfer of Pyongyang's nuclear weapons and bomb fuel to the United States. After their latest meeting, the USA said Kim had agreed to begin detailed negotiations by mid-July.
While North Korea has said it is willing to resume talks, Kim has given a year-end deadline for Washington to take a new approach. North Korea often ratchets up military tensions ahead of negotiations. South Korea's top nuclear envoy was due to go to China, the main benefactor of Kim's government, this week to discuss developments on the divided peninsula.
Kim and Trump met again at the Korean border in late June and agreed to restart diplomacy, but there have no public meetings between the sides since then.More news: United States, China Grant Trade Concessions As Fresh Talks Loom
Observers see North Korea's continued weapons tests as a way to strengthen its diplomatic hand and pressure the U.S.to make more concessions when the two sides resume nuclear talks.
United States President, Donald Trump said on Wednesday that John Bolton who was dismissed as America's national security adviser had been a "disaster" on North Korea policy, "out of line" on Venezuela, and did not get along with important administration officials.
Kim and US President Donald Trump adopted a vaguely-worded statement on the "complete denuclearization of the Korean peninsula" at their first summit in Singapore in June previous year, but little progress has since been made on dismantling Pyongyang's nuclear program.More news: UK Conservatives retain large lead over Labour
