BEIJING — China has struck a hard stance on the issue at the root of the looming trade fight between Beijing and Washington: China’s government-led drive, which Washington describes as breaking international rules, to build the cutting-edge industries of the future.

Chinese officials in recent days have been defending the government’s ambitious plan, known as Made in China 2025, to create globally competitive players in industries like advanced microchips, driverless cars and robotics. While Beijing has signaled a willingness to compromise on other matters, the intractable standoff over its core industrial policy could prolong a trade fight that has already shaken markets and led to concerns about a full-blown trade war.

“We are three years into the implementation of Made in China 2025, and we will keep going,” Miao Wei, China’s minister of industry and information technology, said on Monday, the last day of a three-day economic policy forum in the Chinese capital.

The Trump administration has threatened to impose 25 percent tariffs on imports involving many of the industries being developed under the Made in China 2025 program. Administration officials strongly object to the program’s goal of having Chinese companies dominate these advanced industries, particularly in the Chinese market.

Washington has also protested that companies in the targeted industries have been offered loans at low interest rates by state-controlled Chinese banks. The White House argues that will result in global capacity gluts that could drive down prices and destroy the viability of tech companies in the West, as well as in countries, like Japan and South Korea, that are allied with the United States.

But Chinese ministers and vice ministers contend that their country’s economy is still developing. They openly reject President Trump’s call for reciprocity in trade relations. They have instead offered concessions like raising caps on foreign investors’ stakes in Chinese financial institutions, and proposed eliminating import tariffs in narrow categories like drugs to treat cancer.

Chinese ministers say that opening up some services sectors would improve the efficiency of the Chinese economy as well as make money for foreign companies. Improving health care, particularly for the aging, has also become a national priority.

But Chinese officials argue that their country remains a developing one. It is still dangerously reliant on smokestack industries of the past, like steel, aluminum and cheap manufacturing, they say. The average Chinese household lives on a quarter of the income that American and Western European households do, and standards of living remain very low in rural parts of the country, and across central and western China.

Wang Shouwen, China’s vice minister of commerce, and Pascal Lamy, a former director general of the World Trade Organization, squared off at the Beijing forum over precisely that issue.

Mr. Wang insisted that China had made considerable strides in opening up its health, agriculture and shipping sectors to international competition. He noted that the United States and the European Union had higher tariffs than China on some imports of shirts and dairy products. He argued that China meets its W.T.O. obligations; the W.T.O. has long allowed developing countries to have higher tariffs to protect certain industries from international competition.

Mr. Lamy, a longtime critic of protectionism and government intervention, dismissed those arguments. China — which has the world’s second-largest economy, after the United States, and is the world’s largest manufacturer by far, of everything from steel and cement to laptop computers — had made too much progress to be lumped in with poor countries, he said.

“Pretending it is like India, or like Senegal, or like Botswana is pushing the envelope too far,” Mr. Lamy said. He added that China still had to do more to “ensure a level playing field between Chinese producers and foreign producers, whether they produce inside China or outside of China.”

On crucial issues, China and the United States appear to be talking past each other, not even agreeing on what is being debated.

Take semiconductors, for example.

China is a major customer for microchips, which are used to power computers, smartphones and an ever-widening array of other electronics. Chips from the United States account for just 4 percent of China’s $260 billion in annual chip imports. While Chinese trade officials have been willing to discuss buying more chips from factories in the United States, that could take market share from Japan and South Korea. Washington has resisted that solution.

American officials say the problem is that China’s national, provincial and municipal governments are working with state-owned banks to rush the construction of new factories, particularly to make memory chips.

The new factories often rely on technology that foreign companies have had to transfer as a condition of competing in the Chinese market, according to the United States. Global trade rules ban mandatory technology transfers.

Numerous factories are nearing completion, which will unleash an avalanche of additional output. China contends that it has assisted the sector partly to upgrade its economy and partly because the factories will mainly be supplying its domestic market.

But since factories in China are the world’s main assemblers of electronics, the country’s drive for self-sufficiency in microchips could pose a threat to chip producers in the rest of the world.

For now, China seems to be pinning its hopes on heavy lobbying in Washington by Wall Street, traditionally Beijing’s most reliable ally in bilateral disputes. China’s sovereign wealth fund owns stakes in a variety of American financial institutions. Estimates of Chinese outbound investment over the next decade run as high as $2.5 trillion, a rich source of advisory fees in the United States.

Mr. Wang said on Sunday that China might go beyond its earlier offer to raise caps on foreign ownership in Chinese financial institutions. “It is even possible we will remove those caps altogether” in some categories, he said.

But he also made clear that China would not be intimidated if its offers are not enough to satisfy the Trump administration, which has focused on reviving American manufacturing.

“If China’s interests are impaired,” he said, “we will have to take measures.”
