China's support for the World Trade Organization and free trade is a counterbalance to the loss of momentum for the world economy, said Daryl Guppy, international financial technical analysis expert and special consultant to Axicorp.

The IMF forecast does not adequately assess the contribution of the Belt and Road Initiative to economic growth - not just in developed economies, but in emerging economies as well. In 2008 the world relied on China to lead the way and 2019 will be no different, Guppy said.

China's year-on-year GDP growth reached 6.6 percent in 2018, achieving its goal of around 6.5 percent GDP growth set for the year, the National Bureau of Statistics said on Monday.

With the magnitude and size of the GDP at present, this kind of rate is already very impressive, so it is extremely important for China to maintain its above six percent GDP growth with continuous reform and opening-up and trade with more countries at a fast pace, Wang said.
