Sarkozy-Brown agree deals on defense, climate but are divided over China

French President Nicolas Sarkozy has ended an ambitious state visit to Britain by sealing a multibillion-pound defense deal and vowing to cooperate on issues from pressing the US on climate change to curbing the spread of nuclear weapons technology. But on a rare point of dissonance with his British host, Sarkozy said Thursday he could still boycott the opening ceremony of the Olympic Games in China - something Britain's Prime Minister Gordon Brown insisted he would not do. Sarkozy and Brown showcased their warm friendship during the French leader's 36-hour trip amid pomp, ceremony and promises of a new era of cooperation. As the French president charmed Brown, his glamorous wife - the model-turned-singer Carla Bruni-Sarkozy - captivated the British public with her poise and elegance, winning comparisons with late Jacqueline Kennedy-Onassis.
