US President Donald Trump has said he has "confidence" that North Korean leader Kim Jong-un will honor the denuclearisation "contract" they signed, but that China may be seeking to undermine a deal. The spokesman for the ministry called the talks "really disappointing".
He said the key to Vietnam's rise was post-Vietnam War engagement with the United States, which began in 1985, when the countries started working together to repatriate remains of US service members lost in Vietnam.
However, the North Korean Foreign Ministry later released a lengthy statement that criticized the US focus on nuclear weapons.
However, the spokesman said the USA had come up with a variety of "conditions and excuses" to delay a declaration on ending the war.

Unlike his previous visits, which have been one-day affairs during which he has met Kim Jong-un, Pompeo spent the night at a government guesthouse in Pyongyang and did not see the North Korean leader, although USA officials had suggested such a meeting was expected.
As Saturday's meeting got under way Kim Yong-chol joked that Mr Pompeo may not have slept well during his overnight stay at a guesthouse in Pyongyang.
Pompeo called on North Korean leader Kim Jong Un to replicate Vietnam's "miracle" of economic growth by improving ties with the US, vowing that America keeps its promises with former foes. He later said there was progress in talks, including on setting a timeline for denuclearization, but also acknowledged much work remained to be done.
At the beginning of the meeting, Kim Yong Chol said both sides held "a very serious discussion on very important matters yesterday".
Lawmakers are asking what comes next if talks between the US and North Korea break down, and are looking back to pre-summit practices.
The statement came hours after US Secretary of State Mike Pompeo wrapped up his trip to Pyongyang aimed at hashing out measures to implement the June 12 summit agreement in Singapore, during which their leaders agreed to work towards complete denuclearization of the Korean Peninsula. "If I paid attention to what the press said, I'd go nuts".
There was no immediate explanation of what needed to be clarified but the two sides have been struggling to specify what exactly "denuclearization' would entail and how it could be verified to the satisfaction of the United States".
Pompeo also told Kono he had raised in the talks in Pyongyang, which ended Saturday, the issue of Japanese abducted by North Korea, a major sticking point for Japan in its relations with North Korea. And, he and other USA officials said the two countries, still technically at war after the 1950-53 Korean War, had set up working groups to deal with details of an agreement. She did not elaborate.
"I am determined to achieve the commitment that President Trump made and I am counting on Chairman Kim to be determined to follow through on the commitment that he made", Pompeo said.
US Secretary of State Mike Pompeo, reacting to the provocative statement from North Korea, said that if Washington's demands were "gangster-like", then the world is a gangster.
