Beijing's local government is encouraging private sector to participate in the construction and operation of snow venues for Winter Olympics, government officials said in a recent news conference.

Beijing has 37 indoor skating rinks, 53 outdoor skating rinks, and over 20 ski resorts. It hosted the World Winter Sports Expo in 2018. The capital has also made plans to advance the winter sports industries in the Beijing-Hebei-Tianjin region, he said.

Before the opening ceremony, the two presidents attended a photo exhibition on the achievements of China-South Africa cooperation in science and innovation.

Beijing Daxing International Airport will be qualified to handle flights on Sept 15, taking a big step forward toward its official opening before Sept 30, according to the airport authority on Wednesday.

Beijing has worked strenuously to cut excess production capacity, reduce businesses' leverage and debt ratios and trim local government debt. "We don't see any real sign of a (financial) crisis coming (in China), although we observe excess capacity in some sectors, such as coal and steel, and we've also seen rising indebtedness both in the corporate sector and households.”
