A sharp divide has erupted in the US Senate over President Donald Trump's engagement with Chinese President Xi Jinping, with lawmakers clashing over trade concessions, the artificial intelligence race, religious freedom, and Beijing's alleged transnational repression of dissidents — exposing deep bipartisan fault lines even as the two leaders met publicly.

Republican defence of the summit

Republican Senator Steve Daines defended the meeting, arguing that constructive engagement between the two leaders was essential given that the United States and China are both the world's largest military powers and leading competitors in artificial intelligence. Daines described the bilateral relationship as 'too big to fail' and suggested that Trump's reception for Xi would be read in Beijing as a meaningful gesture of respect.

'It's very important to see both President Trump and President Xi Jinping working in a constructive manner in that public-facing environment,' Daines said. He also noted that US Treasury Secretary Scott Bessent and Chinese Vice Premier He Lifeng had held direct discussions covering trade, AI and Iran.

Daines also sounded a caution, warning that Washington must not underestimate Beijing's technological ambitions. While he acknowledged the US retained an edge in advanced AI model capabilities, he said China was ahead in the pace of adoption. 'We cannot take lightly what China is doing right now in this AI race. It's very important that we continue to lead,' he said.

Democratic criticism: concessions without accountability

Senate Finance Committee ranking member Ron Wyden offered a starkly different reading, accusing Trump of weakening American national security in exchange for limited and, he alleged, unreliable Chinese commitments on agricultural trade and critical minerals. 'In return for China breaking nearly every trade promise it has made, Trump is rolling out the red carpet for President Xi,' Wyden said.

Wyden alleged that China was failing to purchase promised American agricultural goods and was withholding rare-earth minerals needed by US manufacturers. 'Donald Trump is giving away the store to China and leaving American families with the bill,' he said.

Human rights and transnational repression

The summit also intensified congressional scrutiny of Beijing's human-rights record. Democratic Senator Jeff Merkley criticised Republican colleagues for blocking his bipartisan resolution condemning China's alleged repression, coercion and intimidation of critics beyond its borders — including individuals inside the United States.

'Journalists, activists, and everyday people who have spoken truth to power about China's oppression are being bullied, intimidated, and targeted far beyond China's borders,' Merkley said. He argued that defeating the resolution while Xi was on US soil sent the wrong signal. 'I'll keep making the case to my colleagues on both sides of the aisle that we must oppose all acts of transnational repression — no matter the perpetrator,' he added. The resolution had previously cleared committee, and Merkley also leads separate legislation aimed at strengthening the US response to foreign governments that stalk, intimidate or assault diaspora members abroad.

Bipartisan call for religious freedom

In a separate cross-party appeal, senators Chuck Grassley, Ted Budd and Tim Kaine wrote to Trump urging him to press Xi for the release of detained pastors and members of religious minorities in China. Their letter cited the treatment of Tibetan Buddhists, Christians, Uyghur Muslims and Falun Gong practitioners, calling on Beijing to end the harassment of religious organisations and free those imprisoned for practising their faith. 'The United States should continue to promote international religious freedom,' the senators wrote. The letter was co-signed by Merkley and senators Roger Wicker, Peter Welch, Katie Britt, Tim Scott, James Lankford and Ted Cruz.

What comes next

The Senate fractures over the Trump-Xi meeting reflect a broader tension in US China policy — between economic interdependence and strategic competition — that neither party has yet resolved. With trade commitments, AI dominance and human-rights accountability all in play, congressional pressure on the White House is likely to intensify in the weeks following the summit.
