BEIJING — China’s sovereign wealth fund is looking at big bets in America. But the $800 billion investment behemoth said on Tuesday it faced an obstacle: the United States government.

The fund, the China Investment Corporation, urged American authorities to allow better access to the market, at a time when Chinese deals are facing more scrutiny.

“We hope that the U.S. government will provide us with a more liberal, equal and nondiscriminatory investment environment,” said Liu Fangyu, the fund’s managing director and head of public relations and international cooperation.

In some ways, the fund’s interests are aligned with those of the United States.

The Chinese investor is particularly focused on infrastructure, an area where the Trump administration has been pushing for private players to invest more money. And sovereign wealth funds are a good source of financing for such major, long-term deals.
