North Korean leader Kim Jong-Un is expected to announce major policy changes during his New Year’s address on Wednesday.

Some observers say North Korea could use the conference to announce it's abandoning diplomacy with the U.S. and lift its moratorium on major weapons tests.

South Korean military officials didn't immediately say what the weapons were, how many were launched or how far they flew.

The statement by an unidentified North Korean Foreign Ministry spokesperson came as U.S. President Donald Trump visited Japan.

UN ambassador Kim Song said at a news conference Tuesday that the "heinous act" of seizing the ship was aimed at bringing maximum pressure on North Korea to make it "kneel down."

President Donald Trump said on Saturday in a Twitter posting that he believes North Korean leader Kim Jong Un realizes his country's "great economic potential" and "will do nothing to interfere or end it."

Acting Defense Secretary Patrick Shanahan is confirming that North Korea conducted a test launch on Wednesday, but he declined to provide any details.

North Korea said on Thursday it no longer wanted to deal with U.S. Secretary of State Mike Pompeo and said he should be replaced in talks by someone more mature, hours after it announced its first weapons test since nuclear talks broke down.

“If the United States approaches us with the right manner and offers to hold a third North Korea-U.S. leaders’ summit on the condition of finding solutions we could mutually accept, then we do have a willingness to give it one more try,” Kim Jong Un said.

A document seen by Reuters appears to show national security advisor John Bolton's long-held and hardline "Libya model" of denuclearization that North Korea has rejected repeatedly.
