China hopes US national security strategy will promote strategic mutual trust between the two countries, Foreign Ministry spokeswoman Hua Chunying said on Monday, ahead of a major speech on security by US President Donald Trump.

China has witnessed a staggering freefall in the number of international flights after the aviation regulator rolled out orders cutting down flights in and out of the country to curtail the rising number of imported cases of the novel coronavirus.

China is rich in grassland resources - with nearly 400 million hectares of natural grassland accounting for 41.7 percent of the country's land. Protection and restoration of grassland resources will be strengthened, Zhang said.
