Pelosi in China to discuss climate change

BEIJING, May 24 (UPI) -- U.S. House Speaker Nancy Pelosi arrived Sunday in Beijing for a week of discussions with China on global warming.

Pelosi told reporters in Washington her goal is to pave the way for a global agreement on carbon emissions at December's meeting in Copenhagen, The Washington Post reported. She refused to say whether she would bring up criticisms of China's human rights record.

In 1991, two years after the bloody crackdown on student demonstrators, Pelosi waved a banner in support of the protesters in Tiananmen Square. She has also criticized China's record in Tibet.

She will be in China on June 4, the 20th anniversary of the massacre, and a date the Chinese government has been trying to ignore.

Pelosi is the top U.S. official to visit Beijing since Barack Obama became president in January.
