Chinese President Xi Jinping's first full day in London began with a state welcome as he embarked on his four-day stay in Britain, during which more than US$46 billion of deals are expected to be signed. Xi and his wife, Peng Liyuan , exchanged gifts with Queen Elizabeth. The queen gave Xi a collection of Shakespeare's sonnets and Peng a pair of Royal Crown Derby candlesticks, while Xi gave the queen two of his wife's music albums, British media reported. Peng is a popular folk singer in China.

Xi was given an elaborate red-carpet welcome with a 41-gun salute at the House Guards Parade yesterday, greeted by the queen, her husband Prince Philip, and Prime Minister David Cameron.

Amid all the pomp, both sides are expected to sign over US$46.4 billion of agreements - covering industries including retail, energy and aerospace - and creating 3,900 jobs in Britain, the British government said. "Trade and investment between our two nations are growing and our people-to-people links are strong," Cameron said One major deal under discussion is for China to take a key role in a project to build Britain's first new nuclear power station in decades, Hinkley Point C in southwest England. French utility EDF had reached an agreement with Beijing's China General Nuclear and China National Nuclear Corporation to take a 33.5 per cent stake in the project, French daily Les Echos reported. The warming Sino-British relations - particularly London's keen courtship of closer trade ties with Beijing - has drawn criticism that London is not critical enough towards its guest, including on human rights issues. Brookings Institution visiting fellow Philippe Le Corre, an expert on Sino-European ties, said Britain might aspire to be China's Western friend that could be its bridge to the United States. "Just as Britain served as a bridge between Americans and Europeans in the past, it now aims to play such a role with China," Le Corre wrote on the website of Foreign Affairs . "Britain could possibly help China bring the US closer to the negotiating table if the security situation in the Asia-Pacific were to deteriorate as Beijing becomes more assertive." Roland Vogt, director of the University of Hong Kong's European Studies Programme, described Britain as "a central interlocutor for discussions between the US and China". "For Britain, China is part of a broader strategy to enhance the visibility of British diplomacy in Asia," Vogt said. Additional reporting by Agence France-Presse
