Joe Biden will use this week’s G7 summit to encourage allies to join Washington in taking a harder stance towards Beijing, as the US president capped a string of recent actions with an executive order to boost scrutiny of Chinese software and apps.

The escalation of pressure sets the stage for the UK-hosted summit, when Biden hopes to persuade his counterparts to rebuke China over its persecution of Uyghurs in Xinjiang, its crackdown on the pro-democracy movement in Hong Kong, its economic coercion of countries such as Australia, and its aggressive military activity in the South and East China Seas.

As he boarded Air Force One on Wednesday for his first overseas trip as president, Biden said he would use the week in Europe to strengthen alliances and “make it clear to [Russia’s president Vladimir] Putin and to China that Europe and the US are tight”.

The latest executive order, which aims to protect the personal data of Americans, including health and genetic information, was the culmination of weeks of moves by the administration to turn the screws on China.

The Senate this week passed a bipartisan bill that would provide $250bn to help the US maintain a competitive edge over China in critical technologies such as artificial intelligence and quantum computing.

The Pentagon on Wednesday also finished a three-month review of attempts by China to challenge US defence strategy, after concluding that Beijing had become one of its most serious “pacing threats”.

Biden has also taken steps to reduce the dependence of US supply chains on China and last week revamped Donald Trump’s order banning Americans from investing in 59 Chinese companies, including Semiconductor Manufacturing International Corporation, the largest Chinese chipmaker.

“We’ve seen a real commitment by the Biden administration to push back against China,” said Bonnie Glaser, a China expert at the German Marshall Fund. “For many people, the administration has surprised on the upside.”

After attending the G7 gathering in Cornwall, Biden will participate in EU-US and Nato summits in Brussels before meeting Putin in Geneva.

The focus on China came as the US president has faced criticism over his summit with his Russian counterpart, who he recently called a “killer”.

A senior EU official cast the meetings as a vital opportunity to bridge potential divisions and achieve a “balanced approach”.

“[We] expect G7 leaders to commit to better co-operation and align strategies on China,” the official said.

The EU shares many US concerns over China but has been less keen to be part of an overt anti-Beijing alliance. It is also contending with its own tensions with Washington in important areas such as trade and electronic privacy.

The 27-member European bloc and the US intend to “closely consult and co-operate” within “similar multi-faceted approaches to China, which include elements of co-operation, competition and systemic rivalry”, according to draft conclusions for the separate EU-US summit next week.

Shared transatlantic concerns include Xinjiang, Tibet, Hong Kong and security in the East and South China Seas, according to the draft statement, which is subject to revision.

However, Biden will face challenges with some countries concerned about being caught in a growing fight between Washington and Beijing.

“There is persistent concern . . . including in Europe that the US is too confrontational and that the US really is asking countries to choose between the US and China, even though we say we are not,” Glaser said.

In issuing an order to protect US data from China, Biden also revoked a Trump-era ban on Americans using the Chinese-owned apps TikTok and WeChat, which had become neutered after being challenged in US courts.

The new order was intended to provide a mechanism to conduct a “rigorous, evidence-based analysis” to assess the risks posed by software from foreign adversaries, including China, in a way that will survive legal scrutiny, unlike the Trump ban.

“When you consider this new executive order and the investment action from last week, the administration is clearly moving from months of reviews to a period of more sustained action and implementation,” said Eric Sayers, a security expert at the American Enterprise Institute.

“It could be a busy summer.”
