BEIJING, July 31 -- China's computing power networks are expected to receive 4 trillion yuan (589.2 billion U.S. dollars) in new direct investment during the 15th Five-Year Plan period (2026-2030), an official with the country's top economic planner said on Friday.

As computing power development relies mainly on enterprise investment, such development will create enormous room for private investment, Jiang Yi, spokesperson for the National Development and Reform Commission, told a press conference.

China is mulling massive investment in a "Six Networks" initiative as the country works to expand domestic demand and stabilize economic growth.

These six networks comprise water networks, new-type power grids, computing power networks, next-generation communication networks, urban underground pipeline networks and logistics networks.

Jiang said the six networks are not separate systems operating independently, but an integrated whole featuring deep interconnection, mutual empowerment and coordinated support.

During the 15th Five-Year Plan period, about 5 trillion yuan is expected to be invested in underground pipeline networks to accelerate efforts to address weaknesses in gas, water supply and drainage, and heating infrastructure, while enhancing the resilience of urban infrastructure and improving people's quality of life, Jiang said.

In the first half of this year, water network construction attracted more than 10.8 billion yuan in private capital, up 85.8 percent year on year. More projects with stable operating returns will be launched to encourage the participation of private enterprises, according to Jiang.

Construction of the six networks is speeding up, with policy dividends continuing to be unleashed, Jiang noted.
