BEIJING — Top Chinese economic policymakers promised this weekend that Beijing was ready to open up the country’s economy to more market-based competition and international trade, in the latest sign of strong Chinese interest in ending a multibillion-dollar trade war with the United States.

Senior American officials are scheduled to come to Beijing in the coming days for trade talks, with Chinese officials then headed to Washington the following week in an attempt to wrap up a deal.

But Chinese officials have an extra incentive in pledging to loosen their hold over the world’s No. 2 economy, and not just to the Trump administration. In addition to a trade war that is hitting the country’s exporters, China’s economy has also been hurt by private sector business leaders who have become increasingly cautious in recent months about making new investments.

The economy has slowed, creating a self-reinforcing cycle of skepticism that further private investments will be profitable. State-owned enterprises have claimed a growing share of the loans available in the economy, a sign that the government may be crowding out the private businesses that could drive future growth. Xi Jinping, the country’s leader, has insisted that the Communist Party play an ever-greater role in corporate decision making and daily life.
