US, N Korea talks falter

North Korea said yesterday it has "no intention" to continue nuclear talks unless the United States takes steps to end hostilities, a day after negotiations in Sweden broke down.

The discussions in Sweden followed months of stalemate following a February meeting between the North's leader Kim Jong Un and President Donald Trump, and came after Pyongyang's defiant test of a sea-launched ballistic missile on Wednesday.

The North walked away from the Sweden talks saying it was disappointed at the lack of "new and creative" solutions offered by Washington, although the US insisted it was willing to meet again in two weeks.

But a spokesman at the North's foreign ministry said Washington's claims about another meeting was "ungrounded".

"We have no intention to hold such sickening negotiations as what happened this time before the US takes a substantial step to make complete and irreversible withdrawal of the hostile policy toward the DPRK," he said using the acronyms of the North's official name.

In a statement carried by the North's Korean Central News Agency, the spokesman warned that their "dealings" may immediately end if the US sticks to its old playbook.

"The fate of the future DPRK-US dialogue depends on the US attitude, and the end of this year is its deadline," he added.

In Stockholm, the nuclear-armed North's leading negotiator, Kim Myong Gil, blamed the US for not giving up their "old attitude" which led to talks ending "without any outcome".

But Washington called the talks "good discussions", saying the comments by North Korea did not reflect the content or the spirit their eight-and-a-half-hour discussion.

The United States accepted host Sweden's invitation to resume talks in two weeks' time, State Department spokeswoman Morgan Ortagus said.

Ortagus added in a statement that the US "previewed a number of new initiatives" that would allow progress on the statement reached in Singapore at the first Trump-Kim summit last year.

Meanwhile, Chinese President Xi Jinping has promised to promote a "long-term, sound and stable" relationship with North Korea, state news agency Xinhua said yesterday, as the two countries mark 70 years of diplomatic relations.

North Korean leader Kim Jong Un also sent a message to Xi saying their countries' "invincible friendship will be immortal on the road of accomplishing the cause of socialism."
