The new tests came a day after South Korea suspended deployment of a controversial U.S. missile shield - an apparent concession to China, which is strongly opposed to the Terminal High Altitude Area Defense (THAAD) system.
Defying pressure from the worldwide community, North Korea fired four anti-ship missiles last Thursday in what is believed to be a move by the rogue state to demonstrate the precision targeting of its rockets.
Photos taken from what state new agencies claimed was the test launch showed Kim Jong-un wearing a white shirt and grinning while surrounded by lackeys.
"Obviously, the pressure China puts on South Korea has taken effect".
North Korea's latest missile test-that of suspected anti-ship missiles that landed in waters between the Korean Peninsula and Japan- sends a very clear message to America: we're getting ready for war, if it gets to that point.
However, the European Union on Thursday broadened its sanctions against North Korea over its work on nuclear weapons and ballistic missiles.
The launches come less than a week after the United Nations expanded sanctions against Kim Jong-Un's regime in response to the recent ballistic missile tests.
The launches Thursday were North Korea's fourth missile test in as many weeks as the country continues to speed up its development of nuclear weapons and missiles.
All of the weapons on display at the extravagant military parade have been tested in the past month, except for one that analysts said appeared to be an intercontinental ballistic missile, Yonhap news agency reported.
Chung's remarks followed the end of a special probe by the presidential office, which concluded the country's defense ministry had sought to keep the United States missile shield safe from a full-blown environmental impact assessment, which would have taken months before its deployment could begin.
The Security Council voted unanimously on June 2 to add 15 individuals and four entities linked to North Korea's nuclear and missile programs to a United Nations sanctions blacklist.

"North Korea likely wanted to show off its ability to precisely target a large warship, in relation to the joint military drills involving USA aircraft carriers", Roh Jae-Cheon, South Korea's Joint Chiefs of Staff spokesman, told a media briefing.
"The more time North Korea has to develop these systems, the more time it has to develop things that can cause real problems for the U.S", he said. North Korea promised that it would conduct weekly launches-a promise it has largely lived up to.
