In a statement made earlier this month US President Donald Trump said that he would be "honoured" to meet his Korean counterpart, Kim Jong-Un.
"We'll have dialogue if the conditions are there", said Choe Son Hui, North Korea's foreign ministry director general for United States affairs, to reporters in Beijing as she was travelling home from Norway.
Amid simmering tensions on the Korean Peninsula, a senior North Korean diplomat in charge of handling United States relations says Pyongyang would hold talks with Washington under the right conditions.
Such rhetoric is in contrast with the sharp tensions between the United States and North Korea.
Trump's administration since then has said that Pyongyang must agree to abandon its nuclear and missile programme before relations between the countries can improve.
South Korea and the USA enforced the FTA in 2012 after years of grueling negotiations.
The official, who was next to Moon as he spoke with Trump, also said the USA president mentioned the trade issue "in a light fashion, mentioning it on a principle level" and added that the "focus was on the North Korean nuclear issue".

South Korea's newly elected President Moon Jae-in has also expressed willingness to visit Pyongyang under the right circumstances.
Although Moon has been linked to a more conciliatory approach to North Korea after his election, there have so far been no indication he would cut back on military spending.
Boyle said Moon would have no choice but to accept USA military diktats because of Washington's massive armed presence in his country.
On holding a dialogue with South Korea's new President Moon Jae-in, Choe said: "We will observe the situation".
"I've committed to devoting my last drop of blood to this work", he said in an online post, according to Reuters, as he was raising money through churches to fund his trip and service to North Korea. The missiles appear to be the same KN-17 scud variant that failed in recent launches.
