Chinese vice premier Liu Yandong reiterated Beijing's offer of assured delivery and great prospects for winter sports during a presentation to the International Olympic Committee (IOC) at the 2022 Olympic Winter Games Candidate City Briefing in Lausanne, Switzerland on Tuesday.

The eight-member panel put forward a strong case for Beijing, explaining how the bid embraces the Olympic Agenda 2020 principles through its concept of athlete-centered, sustainable and economical Games, while offering much more: an opportunity to grow winter sports in one of the biggest markets in the world, as well as an enjoyable atmosphere of a big cosmopolitan city and an exceptional mountain setting at the foot of the Great Wall.

One behalf of the Chinese Government, the vice premier confirmed the full government support for Beijing's bid.

"We have always be a loyal partner with the IOC," she said. "The Chinese people are passionate about the Olympic Winter Games and they are eager to contribute to the Games."

According to Liu Yandong, Beijing's bid will promote Olympic solidarity, friendship and peace among the Chinese people, encourage over 300 million Chinese to participate in winter sports and promote healthy lifestyles in China.

"We are upgrading the Chinese Olympic Museum, and we will make the International Winter Sports Expo as an annual event," the vice Premier said.

International Olympic Committee President Thomas Bach said that in today's presentations at the 2022 Candidate Cities Briefing for IOC members: "Beijing showed excellent use of the 2008 legacy'' of hosting the Summer Olympics.

He also said that Beijing plans to create a "sporting legacy by giving more than 300 million Chinese access to winter sports''.

Commenting on the presentations by Beijing and Almaty, he said: "It was really impressive to see how both cities had embraced the reforms of Olympic Agenda 2020 just six months after the recommendations were unanimously approved by the IOC.

"You could see a clear focus in both bids on sustainability and affordability. Both presented very well balanced budgets, and both clearly demonstrated what they wanted to achieve, following Olympic Agenda 2020, by building their proposals into the long-term development plans of their city, region and country.''

Bach said both cities had different approaches and are "starting from different points'', with Almaty planning to develop a traditional winter sports center that will leave the "lasting legacy of transforming the region''.

"On the other hand, Beijing showed excellent use of the 2008 legacy, and also plans to create a sporting legacy by giving more than 300 million Chinese access to winter sports,'' he added.

"It (Beijing) would be the safest decision for the International Olypic Committee (IOC) to choose Beijing, which is the most reliable partner for all stakeholders," mayor Wang Anshun told the IOC members.

Illustrating the legacy of the Beijing 2008 Olympic Games, Wang told the IOC members that the city of Beijing has fully embraced the Olympic spirit and "experience it every day".

"With strong public support, government guarantee, sound natural conditions, comprehensive experience in Games organization and your guidance, we are confident that all potential risks could be effectively managed," he added.

According to the mayor, Beijing has established an Olympic City Development Association and a fund after the 2008 Games. The average use of the 2008 venues, however, exceeds 85 percent annually.

Wang also emphasized that in the past few years, more than half of Beijing's population participated in sports and 2.6 million registered volunteers played active roles to enhance city development as well as quality of people's lives.

As to the smog issue, one of the major concerns from the media, mayor Wang explained that Beijing has invested $130 billion in a five-year comprehensive clean air action plan since 2013.

"It would be a beautiful natural environment with blue sky that greets the visitors in Beijing by 2022.

"We are confident about that," he said.

China's central and local governments in Beijing and Zhangjiakou have included Beijing 2022 in the National Strategy of Integrated and Coordinated Development of the Beijing-Tianjin-Hebei Region (National Strategy), and the long-term regional development plans, thereby facilitating the bidding and preparation for the Olympic Winter Games, the improvement of urban ecological environments and the close integration of economic development and social advancement.

Moreover, Beijing stresses an economical Games. The Bid Committee has adhered to the principles of being scientific, meticulous, prudent and feasible in the budgeting for the Games. Out of the 12 competition and non-competition venues in Beijing, 11 are existing venues inherited from the Beijing 2008 Olympics.

The delegation for the other candidate city, Almaty in Kazakhstan, held its first round of scheduled presentations before Beijing.

"During the presentations we showed our map and we presented in detail our existing venues," a member of the Almaty delegation said after the meeting, which also saw the central Asian delegation answer questions from the 85 IOC members.

The official said that they answered all the IOC questions "both honestly and frankly".

According to the 2022 Evaluation Commission's report released earlier this month, Almaty's vision is to contribute to the Kazakhstan 2050 development plan, enhance the population's health as well as the country's international profile while delivering the games which can be used as model for sustainable and affordable games in the future.

Tuesday is the first of two days of crucial presentations, where both candidate cities Almaty and Beijing will try to impress IOC members ahead of the decisive July 31 vote during the committee's 128th session in Kuala Lumpur this year.
