Han, a member of the Standing Committee of the Political Bureau of the Chinese Communist Party, currently chairs China’s Winter Olympics Working Leading Group.

The official has urged organisers to work efficiently to deliver safe and secure Games, with less than three months until the Opening Ceremony of the Winter Olympic Games.

"The Winter Olympics Organising Committee must implement the main responsibilities, and all relevant parties must perform their duties and cooperate closely to form a strong work force to ensure the efficient and orderly operation of the Games," Han said in a statement published by the Chinese Government.

"It is necessary to strictly implement various measures for epidemic prevention and control, adhere to the comprehensive integration and integration of the Winter Olympics and the host city's epidemic prevention and control, and further improve relevant prevention and control plans to ensure the safety of the event.

"It is necessary to do a good job in the construction and operation of venues, provide high-quality match service guarantees, and earnestly guarantee the operation of the city.

"It is necessary to continue to run the international test competition, conduct all-element tests in accordance with the Winter Olympics standards, and properly make the transition to the competition time.

"We must do a good job of preparing for the Winter Olympics and do anti-doping work with a zero tolerance attitude.

"We must carry out publicity, promotion and cultural activities, and do a good job in fire display, Torch Relay, and Opening and Closing Ceremonies.

"It is necessary to coordinate the preparations for the Winter Olympics, economic development and people's livelihood, and ensure the smooth and orderly coordinated progress of all aspects of work."

COVID-19 countermeasures remain a central issue prior to the Games, amid the ongoing pandemic.

Organisers released the first edition of a playbook last month, which outlines rules all Olympic participants must adhere to during the Games.

All those who are fully vaccinated against COVID-19 will not need to quarantine for 21 days upon arrival in China and can instead enter a "closed-loop management system".

Those inside the closed-loop management system will be tested daily for COVID-19 and may only visit approved locations using approved means of transport.

The system will apply to all three Olympic zones in Beijing, Zhangjiakou and Yanqing and will be in place throughout the participants' stay.

A second version of the playbooks are expected to be released next month.

Details on travel arrangements to the Games are also expected in the coming weeks, amid concerns over a lack of flights to China.

China has heavily restricted international travel as the nation attempts to curb COVID-19 cases.

Beijing 2022 and the International Olympic Committee has said 15 airlines are expected to operate temporary flights to China for the Games, with four hubs expected to assist Games participants.

Juan Antonio Samaranch, chair of the IOC Coordination Commission for the Games, said there had been positive feedback from International Federations regarding test events taking place in China.

Test events for speed skating, figure skating, short track speed skating, wheelchair curling, bobsleigh and skeleton were held last month.

International events for luge, freestyle skiing and snowboard are due to take place this month, with ice hockey activities also held.

The Winter Olympics are due to take place from February 4 to 20, with the Paralympic Games scheduled to follow from March 4 until 13.
