The visit to China this week by the U.S. Speaker of the House Nancy Pelosi, one of the strongest critics of Beijing's human rights record in the last two decades, has spurred speculation as to what she might do during the trip, the official purpose of which is to discuss climate change.
Ms. Pelosi declined at a briefing to say whether she planned to discuss human rights, saying only that she wanted to secure support for a global pact on reducing carbon emissions, in advance of a major international gathering on climate change scheduled for December in Copenhagen.
