Brexit means Brexit. But the full effects of Britain's decision to leave the European Union will only be seen by 2020. That's the view of Lord Meghnad Desai, a professor emeritus at the London School of Economics and chairman of the Advisory Board of the Official Monetary and Financial Institutions Forum.

Desai recently wrote that there's little chance of a second EU referendum. Desai also said the Chinese investment and construction of the controversial 18 billion pound Hinkley Point C nuclear power plant in the UK should continue. That's despite reported concerns from new British Prime Minister Theresa May about national security. CCTV reporter Martina Fuchs caught up with Desai in Beijing.
