Product Application Cases
Qatar Hamad International Airport Phase B expansion project
Hamad International Airport, formerly known as the New Doha International Airport, is located in the Middle East, Qatar's capital city of Doha, an international airport. Hamad International Airport put into operation in 2014, is one of the most advanced facilities in the Middle East, the largest passenger throughput of the aviation hub. The Phase B expansion of the airport is under way, including the construction of 11,000 square metres of new retail and dining areas and a 10,000 square metre indoor garden, as well as a new cargo terminal with a capacity of 60 million passengers per year. Once completed, the airport's annual passenger capacity will increase to 70 million, with the Middle East expected to double by 2040, according to the latest International Air Transport Association data.
Indonesia Jakarta-Bandung high-speed rail project
Connecting Jakarta, the capital of Indonesia, and Bandung, the fourth largest city in Indonesia, the Jakarta-Bandung high-speed Railway is the first high-speed railway in Southeast Asia and the first high-speed railway construction project with the whole system, all elements and the whole industrial chain of China's high-speed railway overseas.
In 2016, the Jakarta-Bandung high-speed rail project was officially launched, and under the personal promotion of the heads of state of China and Indonesia, the construction of the Jakarta-Bandung high-speed rail has continued to advance and made significant progress. As a landmark project of high-quality Belt and Road cooperation between China and Indonesia, the Jakarta-Bandung high-speed rail is a vivid illustration of the rich connotation of building a China-Indonesia community of shared future, and a vivid illustration of China and its neighbors working together under the principle of extensive consultation, joint contribution and shared benefits to deepen mutually beneficial and win-win cooperation.
Recently, the Jakarta-Bandung high-speed railway with a total length of 142 kilometers has reached 350 kilometers per hour for the first time, and the maximum speed reached 386km/h, marking that the Jakarta-Bandung high-speed railway has reached the design speed standard. The completion of the railway has witnessed the vigorous development of bilateral relations and become a vivid epitome of cooperation between China and economies in the Asia-Pacific region.
