Britain and China could sign deals worth more than US$30 billion this week during a visit to the UK by Chinese Premier Li Keqiang, Reuters reported, citing Chinese officials. China views Britain as Europe’s most open economy and is keen for its firms to invest in nuclear and high-speed rail projects. It also wants the government to ensure London’s Heathrow airport is expanded. Two large Chinese investment funds are expected to announce plans to plough new money into Britain during the trip. Political tensions remain, however. Beijing reminded London ahead of Li’s trip not to interfere in China’s domestic affairs.
