"Today…China is the second most important market in the world (only after the United States). It's been growing extremely strong over the last 25 years, but we have to be even more ambitious. China's growing so fast that we hope that China can become an even more important destination for diamonds than it is today," said AI Cook, CEO of De Beers Group.
