Politicians in the UK, the U.S. and elsewhere who demonize China see the world as black and white, so it is they who are naive, says Sir Sherard Cowper-Coles, former British ambassador to Israel, Saudi Arabia and Afghanistan. He is now chair of the China-Britain Business Council. In an exclusive interview with Tian Wei in Beijing, Cowper-Coles predicts China will be the world's largest economy amid efforts to shift the Chinese economy to high-quality growth.
