The annual gathering sets development priorities for the upcoming year.The meeting pointed out that, while recognizing achievements, the country must be clearly aware of the changes caused by the pandemic and uncertainties abroad, state media said.”The foundation of our economic recovery is not yet solid,” the report said, according to a CNBC translation of the Chinese text.Covid-19 first emerged in the Chinese city of Wuhan late last year. In an effort to control the outbreak, Chinese authorities briefly shut down more than half the country early this year. GDP contracted by 6.8% in the first quarter, before returning to growth in the second quarter at 3.2%.”Not yet having a solid (foundation) points to the slightly slower-than-expected launch of domestic demand and consumption,” Bruce Pang, head of macro and strategy research at China Renaissance, said in a Chinese statement, according to a CNBC translation.Investment in manufacturing and the share not tied to the state hasn’t rebounded strongly, Pang said. He added there are doubts about the sustainability of exports, uncertainties about employment and many other concerns.Economists have pointed out that much of China’s recovery has come from traditional drivers of growth such as exports, which have been boosted by overseas demand for pandemic-related products.But many Chinese have yet to step up their spending amid concerns about future income. That lack of consumption is concerning for an economy that Beijing is trying to support more with domestic, rather than foreign, demand.While China is on pace for roughly 2% growth this year, retail sales through the end of November are down 4.8% from a year ago.”Next year, the speed of economic growth may slow after an initially rapid pace,” state media said, according to a CNBC translation of the Chinese text. “Keeping the economy operating in a reasonable range remains a key test.”GDP expansion in the first few months of next year would look high compared with the contraction in the first quarter in 2020. Overall, many economists predict China’s GDP will grow about 8% next year.Pang pointed out that rate would be equivalent to 5% growth in 2020 and another 5% increase in 2021.That’s slower than the 6.1% pace in 2019.
