China will step up efforts in the construction of major projects and new infrastructure as part of its overall drive to foster long-term, sustained, innovation-driven and high-quality development, the country's top economic regulator said on Monday.

  Experts said the government has already introduced a series of stimulus policies for infrastructure spending to shore up growth, and its accelerated push to construct key projects will help boost domestic demand, expand effective investment and stabilize the overall economy.

  They said China's economy will continue to pick up in the third and fourth quarters of the year with existing policy support and forceful infrastructure spending.

  The country will support the construction of major projects, with a key focus on implementing 102 key projects mapped out during the period of the 14th Five-Year Plan (2021-25) and projects in the five-year plan for transportation development, said Zheng Jian, director of the Department of Infrastructure Development at the National Development and Reform Commission.
