Trump upbeat about meeting with DPRK's Kim

QUEBEC CITY - US President Donald Trump said Saturday that he will attend the upcoming meeting with the top leader of the Democratic People's Republic of Korea (DPRK) Kim Jong-un with "positive spirit."

Describing his talks in Singapore with Kim as entering "unknown territory," Trump told reporters before his early departure from the G7 summit in Quebec city, Canada, that he really feels confident.

"(It's) never been done,(it's) never been tested. So we are going in with a really positive spirit," the US president said.

Trump and Kim are expected to meet in Singapore on Tuesday with talks focusing on the denuclearization of the Korean Peninsula.

Calling his Asian trip a "mission of peace," Trump told reporters, "I think it's gonna to work very well." However, he cautioned that it will be "a process" when it comes to the denuclearization.

Trump revealed that the US team had worked "very well" with the representatives from Pyongyang during the bilateral preparatory talks for the summit.

Trump will travel directly to Singapore from Canada to attend the meeting. He said earlier this week that his stay length in Singapore would be decided "depending on what happens."

The back-on-track summit followed a whirlwind of diplomacy after Trump called off the meeting in late May.
