What’s the reason for the conflict between China and the Great Britain?

British Foreign Secretary David Miliband is in China on a three-day visit, seeking to smooth the rift between Britain and China following British anger over the Copenhagen climate talks and China’s execution of a British citizen, Peter Simpson reports from Beijing. British Foreign Minister David Miliband is seeking to reconcile differences with China. Like U.S. Deputy Secretary of State James Steinberg two weeks ago, Miliband would also seek to push China to agree to sanctions against Iran. Miliband says he and high-ranking Chinese leaders will be discussing how the UN Security Council can, as he says, address the real threat that the Iranian nuclear program poses to international stability and security.
