North Korea's delegate to normalization discussions with Japan said Tuesday he is hoping for the best from talks with his Japanese counterpart to be held in Ulan Bator this week.

"I would like to refrain from commenting on the outlook before it happens," Song Il Ho said after arriving in Beijing on his way to Mongolia.

But "it has been six months since talks in Hanoi, so I have a certain level of expectations," he added, referring to the last session of talks on diplomatic normalization that were held in Hanoi.
