WASHINGTON (Reuters) -U.S. senators from both major parties plan to introduce bills this week targeting China over its treatment of minority groups, dissidents and Taiwan, emphasizing security and human rights as President Donald Trump focuses on trade with Beijing.

The three bills, seen by Reuters ahead of their introduction, have Democratic and Republican sponsors, a departure from the fierce partisanship dividing Washington.

The Chinese Foreign Ministry on Tuesday expressed opposition to the bills, calling them "a gross interference in China's internal affairs" and demanded a halt to the "erroneous bills" advancement and deliberation.

Trump's push to reach economic agreements between the world's two biggest economies has strong support in the U.S. Congress, especially from his fellow Republicans, but has prompted some China hawks to worry that the U.S. government is de-emphasizing security issues.

"It does appear that President Trump is keen to negotiate some kind of deal with China, and gaps are opening between his approach to China and the approaches of some members of his team, as well as with Congress, which overall has been quite hawkish on China," said Bonnie Glaser, an Asia expert at the German Marshall Fund of the United States.

The desire for a hard line on China is one of the few truly bipartisan sentiments in the perennially divided Congress, even as many lawmakers support Trump's efforts to rebalance the bilateral trade relationship.

"The United States cannot afford to be weak in the face of the People's Republic of China and its aggression around the world," said Democrat Jeff Merkley of Oregon, a lead sponsor of all three bills.

"No matter who is in the White House, America's values of freedom and human rights must remain at the heart of a clear and principled vision that guides our leadership on the global stage," Merkley said in a statement.

Trump administration officials have said that Trump remains fully committed to Asia-Pacific security issues as he pursues his trade agenda and a good personal relationship with Chinese President Xi Jinping.

Asked for comment on Monday, White House Deputy Press Secretary Anna Kelly said administration officials do not get ahead of the president on pending legislation.

"President Trump has publicly discussed his desire for a constructive relationship with China. He is focused on advancing American interests, such as leveling the playing field for American industries and getting China to stop the flow of fentanyl into our country," she said via email.

TRADE VS. SECURITY

One bill, co-sponsored by Republican John Cornyn of Texas, would deny entry into the United States of current or former Chinese government officials who were deemed to have engaged in the forced repatriation of members of China's Uyghur minority.

Human rights groups accuse China of widespread abuses of Uyghurs, a mainly Muslim ethnic minority numbering about 10 million in its northwestern region of Xinjiang. Beijing denies any abuses.

Another bill, co-sponsored by Republican John Curtis of Utah, aims to help Taiwan as the island faces increasing pressure from China. It would support countries in Latin America and the Caribbean that maintain official diplomatic relations with Taiwan and would take other steps to deepen coordination with Taipei.

China claims the democratically governed island as its own and has never renounced the use of force to bring Taiwan under its control. Beijing has stepped up military and political pressure against the island in recent years.

A third bill, co-sponsored by Republican Dan Sullivan of Alaska, seeks to combat "transnational repression" - efforts by any foreign government to reach beyond its own borders to intimidate, harass or harm dissidents, journalists or activists.

China's foreign ministry, in a response to the bills, said on Tuesday that China has never engaged in so-called "transnational repression" and rejected U.S. accusations regarding Taiwan and Xinjiang.

"The related accusations are entirely fabricated and are malicious slander," the ministry said. It urged U.S. politicians to abide by the one-China principle and stop using human rights as a pretext to smear and attack China.

Facing Trump's August 12 deadline, top U.S. and Chinese economic officials are meeting in Stockholm on Monday to try to tackle their longstanding disputes, hoping to extend a truce by three months and keep sharply higher tariffs at bay.

Trump "cares about opening foreign markets to American trade, and that's what he's always cared about. And that is going to run counter to a lot of national security imperatives," said Michael Sobolik, who specializes in U.S.-China relations at the Hudson Institute.

Democrats and some of Trump's fellow Republicans raised concerns about the announcement this month that Nvidia ( NVDA ) will resume sales of its H20 artificial intelligence chips to China, days after its CEO met with Trump. This reversed an AI restriction imposed in April that was designed to keep the most advanced AI chips out of Chinese hands.
