HIROSHIMA — Lower house speakers from the Group of Eight nations promised Tuesday to strengthen efforts to uphold and reinforce the Nuclear Nonproliferation Treaty, which comes up for review in 2010.

But despite lofty promises of unity in support of long-term nonproliferation efforts, the Hiroshima meeting was marked by political divisions over clashes between Russia and Georgia, as well as concerns over a nuclear deal between the United States and India.

"There were strong statements from several speakers that we needed to uphold and reinforce the (nuclear) nonproliferation regime," said Lower House Speaker Yohei Kono at a wrap-up news conference Tuesday evening.
