PYONGYANG, July 1 (Xinhua) -- The Democratic People's Republic of Korea (DPRK) on Sunday denounced Japan for suppressing a main pro-DPRK organization Chongryon, and suggested it could reject Tokyo's presence at the six-party talks on the nuclear issue, the DPRK's official news agency reported.

    The building and land owned by Chongryon were due to be auctioned off at the request of Japan's government-affiliated Resolution and Collection Corp., which took over bad debts from a collapsed Pyongyang-linked credit union in Osaka. The credit union held a mortgage on the building and the land.

    "(The Japanese authority's) anti-Chongryon campaign has reached such a reckless and hideous phase that it can never be tolerated," the Korean Central News Agency(KCNA) quoted a DPRK Foreign Ministry statement as saying.

    "(Tokyo) instructed the corporation to raise an extremely discriminative and unfair demand to Chongryon, persistently turning down its sincere and reasonable proposals to redeem debts," said the statement. "It has thus unilaterally hamstrung Chongryon's efforts for the solution of the problem."

    The statement said Japan's true aim is to block the six-party talks on the nuclear issue on the Korean Peninsula.

    "The aim sought by Japan in chilling the efforts to bring about progress at the six-party talks ... is to drag on the settlement of the problem in a bid to use it as a pretext till its militarization has become a reality," it said.

    "The DPRK cannot but raise a serious question as to whether there is any need for its continued participation in the six-party talks," it added.

    Chongryong is the biggest pro-Pyongyang organization in Japan, whose members are descendants of Koreans abducted by Japan during World War II.
