London, Muharram 8, 1437, Oct 21, 2015, SPA -- Prime Minister David Cameron and Chinese President Xi Jinping were expected to oversee the signing of agreements worth billions of dollars on Wednesday, led by Chinese investment in Britain's nuclear power industry, dpa reported. Cameron and Xi were expected to focus on economic topics during their talks, as British media speculated that Chinese investment could cover up to one-third of the cost of building two nuclear plants at the Hinkley Point site in the south-west of the country. --SPA 14:26 LOCAL TIME 11:26 GMT www.spa.gov.sa/w
