The general concept for "nuclear- free" should be "nuclear-weapon-free", Chinese Deputy Foreign Minister Wang Yi said in Beijing Saturday.

Wang made the remark at a press briefing following the end of the second round of six-party talks about the Korean Peninsula issue.

In reply to a reporter's question about the definition of " nuclear-free Korean Peninsula", Wang clarified that there are many nuclear-weapon-free zones in the world, so an accurate concept for the "nuclear-free Korean Peninsula" should be a "nuclear-weapon- free Korean peninsula".
