China is deepening reform and opening up comprehensively, according to a government work report submitted on Wednesday to the national legislature for deliberation.

The report said China has fully applied the negative list for cross-border trade in services and launched opening-up trials for valued-added telecom services, biotechnology and wholly foreign-owned hospitals.

In line with its increasing unilateral opening up, China has given all the least developed countries with which it has diplomatic relations zero-tariff treatment for 100 percent tariff lines, it said, adding that the country extended the permitted stay for eligible foreign travelers who transit to a third country or region to 240 hours.

The high-quality Belt and Road cooperation has achieved remarkable results, and many major projects on improving people's livelihood have been steadily implemented, it said.
