British Prime Minister David Cameron will lead the country's biggest-ever business delegation to China to focus squarely on expanding trade ties between the two countries.

The delegation leaves London on Monday for Beijing, and is expected to meet with President Hu Jintao and hold talks with Premier Wen Jiabao. The meetings comes ahead of this week's G20 Summit in South Korea.

Britain's delegation includes more than 40 business leaders and four of senior ministers from the Conservative-Liberal Democratic coalition government. Cameron hailed the trip to China as an "important trade mission", aimed at promoting Britain as "open for business". He added that his government wanted "much stronger relations with China" to help make Britain a "successful, open, trading and pro-business country".
