Japan's chief negotiator at the Kyoto conference in Nairobi Monday called on China to let the United Nations know what it is doing about greenhouse gases.

Mutsuyoshi Nishimara said China appears to be making great progress but needs to "the commitment and do the job."

Nishimara rejected calls to punish those countries violating clean air rules.

"We lose the battle the moment we seek to punish countries for noncompliance," Nishimara said.

The 2-week conference, the 12th Conference of the 189 Parties to the U.N. Framework Convention on Climate Change and the second meeting of the 166 Parties to the Kyoto Protocol, is the first U.N. climate summit in sub-Saharan Africa and is expected to draw around some 5,000 participants. The conference runs through Nov. 17.
