Beijing will invest a record 262.6 billion yuan ($40.3 billion) in 210 major projects this year, a city official said on Wednesday.

Xu Xi, deputy secretary-general of the Beijing Municipal Government, said overall investment in the projects, 95 of which are new, stood at 1.2 trillion yuan.

According to the plan, 49 percent of the construction of the new international airport in Daxing district and 12 percent of the high-speed railway connecting Beijing and Zhangjiakou, the two host cities of the 2022 Winter Olympics, will be finished by the end of this year.

In addition, nearly 60 percent of projects related to the Beijing municipal administrative center in the city's eastern suburb Tongzhou district will also be completed within nine months.

The municipal government will move to the new administrative center at the end of 2017.
