Rishi Sunak: China represents challenge to world order

China "represents a challenge to the world order" which the UK must take seriously, Rishi Sunak has said.

The prime minister told the BBC he was increasing funding for the armed forces because "the world has become more volatile" and "threats to our security have increased".

Defence spending will rise by nearly £5bn over the next two years.

But No 10 has given no timeframe for a longer term ambition to boost spending to 2.5% of national income.

Mr Sunak was speaking in California, where he held talks with his US and Australian counterparts to agree details of a UK-US pact to supply Australia with nuclear-powered submarines.

The agreement, known as the Aukus pact, was signed in 2021 as part of a joint effort to counter Chinese military power in the Indo-Pacific region.

Mr Sunak said in a press conference to mark the pact that the Aukus partnership would deliver "one of the most advanced" submarines "the world has ever known", creating thousands of jobs in British shipyards.

The new SSN-Aukus submarines will also be used by the UK, and will be in operation for the Royal Navy by the late 2030s under the plan.

The boats will replace the UK's seven Astute-class subs.

The UK's submarines will mainly be built by BAE Systems at Barrow-in-Furness, Cumbria, and Rolls-Royce, with the US sharing sensitive technology for the project.

Australia's boats will be built in South Australia, using some components manufactured in the UK, and will be in service in the early 2040s.

Mr Sunak said: "The Aukus partnership, and the submarines we are building in British shipyards, are a tangible demonstration of our commitment to global security.

"This partnership was founded on the bedrock of our shared values and resolute focus on upholding stability in the Indo-Pacific and beyond."

'Another hollow promise'

Earlier, in an interview with the BBC's Chris Mason, Mr Sunak said: "China is a country with fundamentally different values to ours and it represents a challenge to the world order.

"And that's why it's right that we are alert to that and take steps to protect ourselves… stand up for our values and protect our interests."

He said the government took the "challenge" posed by China seriously, adding that the UK had taken action including blocking Chinese investment in sensitive sectors like semiconductors.

Pressed on whether the ambition to increase defence spending to 2.5% of national income was meaningless without a timeframe, the prime minister said the government should be judged "on our actions".

As chancellor, Mr Sunak said he had overseen the largest uplift in defence spending since the end of the Cold War and the government had increased spending every year since then.

"We're one of the largest spenders on defence anywhere in the world, the largest in Europe, and that will continue to remain the case," he added.

However, Labour pointed out that defence spending had not hit 2.5% of GDP since it left government in 2010. The UK currently aims to spend 2% of GDP on defence each year, latest figures show.

Shadow foreign secretary David Lammy described the ambition as "another hollow promise", with "no plan and no timetable".

Some Tory MPs have also expressed concern about the level of investment in the armed forces.

Tobias Ellwood, who is chairman of the Commons Defence Committee, said the UK was on a "peacetime budget" as the world was "sliding towards a new Cold War".

While Defence Secretary Ben Wallace has publicly welcomed the extra £5bn announced by the prime minister, he had been hoping for considerably more.

There had been reports - denied by Mr Wallace - that he had threatened to resign if he did not get a commitment to increase defence spending to 3% of GDP by 2030.

Mr Wallace told the Commons he was "not interested" in resigning, although he added that he was worried about the increased threats facing the UK and long-term investment was needed.

Hulking floating airports, aircraft carriers, dominate the shoreline on the Pacific Coast of the United States, where there is a gathering of what's known as the Aukus pact: Australia, the United States and the United Kingdom, keeping a collectively nervous eye on an increasingly muscular China.

Privately, the government is stark in its assessments.

Western democracies are comparatively and collectively weaker economically as China grows; Beijing can use every instrument of the state as a tool of foreign policy in a way that's impossible in an open democracy.

All the data make us more concerned, not less, as one senior figure put it. The review of foreign and defence policy, which has just been published, says the UK is committed to "swift and robust action" to counter any threat to UK national interests from China.

Mr Sunak was also asked whether Chinese-owned social media app TikTok should be banned on all government phones.

It comes after the Sunday Times reported experts at GCHQ's National Cyber Security Centre had identified risks to sensitive information from the app and could issue advice to ministers and civil servants.

The prime minister refused to comment directly but said "we take the security of devices seriously and we look also at what our allies are doing".

The US government and the European Commission have already taken steps to ban TikTok on the phones of staff members.

'Overdue'

The government has set out its plans for foreign and defence policy in an new version of the so-called Integrated Review.

The update was ordered by then-Prime Minister Liz Truss in September last year to take account of Russia's invasion of Ukraine.

The review identified Russia as "the most pressing national security and foreign policy priority in the short-to-medium term".

But it also describes China under Communist Party rule as an "epoch-defining and systemic challenge... across almost every aspect of national life and government policy".

It says the government will engage "constructively" with Beijing on shared priorities but where the Chinese government's actions threaten the UK's interests "we will take swift and robust action to protect them".

Former Conservative leader Sir Iain Duncan Smith, who is among the Tory MPs calling for the government to take a tougher line on China, said he was "confused" about what the government's position was.

"Does that now mean that China is a threat or an epoch-defining challenge or a challenging government epoch or none of that?" he asked in the Commons.

Mr Lammy said the updated review was "overdue" but welcome.

"The initiative to improve understanding of China in government is vital, particularly given the Foreign Office has only been training 14 people a year to speak fluent Mandarin," he added.
