From 2014 to 2019, China's trade in services grew at an average annual rate of 7.8 percent－2.2 times that of trade in goods and 1.9 times that of the growth of its total foreign trade.

The development of China's trade in services will also create immense room for win-win cooperation between different countries and regions and serve as an important engine for bilateral and multilateral trade, he said.

For instance, there is still huge potential for the growth of China-EU services trade, which accounted for only about 12.6 percent of their total trade volume in 2018, he said.

"If the proportion of China-EU services trade increases to the global average level of 23.8 percent, their services trade volume will reach $167.8 billion, and if it reaches 30 percent, the volume will shoot up to $211.5 billion," he said.

"China, with a population of 1.4 billion people, will continue to be a huge market for the world, shared by the world, and a market that benefits everybody," he said.
