(Reuters) - Chinese President Xi Jinping heaped praise on Britain for what he called a "visionary and strategic choice" to strengthen commercial ties with China, as he prepared for a state visit to the United Kingdom that's expected to be richer in pomp and considerably warmer in tone than his recent trip to the United States.

The trip comes at a time of global anxiety about China's slowing growth. Xi himself acknowledged "concerns about the Chinese economy", but sought to allay them in a written interview with Reuters.

China itself is worried about the slowing of the broader global economy, Xi said, even while he expressed confidence that China would weather the current downturn as it reshapes its economy to be more resilient in the future.

That confidence will be on display when Xi arrives in London on Monday evening to kick off a four-day visit that is expected to cement ties between Britain and China, including through a host of business deals.

"The UK has stated that it will be the Western country that is most open to China. This is a visionary and strategic choice that fully meets Britain's own long-term interest," Xi said in a written response to questions from Reuters.

"China looks forward to engaging with the UK in a wider range, at a higher level and in greater depth."

Warmer Welcome

Xi's visit comes amid debate in Britain and many other Western countries over what is the best way to engage with a Communist-ruled China that has grown more influential economically and diplomatically, but which maintains stances in areas from human rights to the South China Sea that are often at odds with those widely held in the West.

Such tensions were on display when Xi visited the United States last month, with friction over issues from cyber theft to China's maritime disputes with its neighbors at the center of discussions.

Xi's visit to Britain, during which he and his wife Peng Liyuan will stay at Buckingham Palace as guests of Queen Elizabeth II, is expected to be much warmer, with Xi saying it could be the start of a "golden time" in bilateral relations.

Britain was the first Western nation to join the China-led Asian Infrastructure Investment Bank (AIIB) earlier this year, leading to a stampede of other countries signing up and marking an embarrassment for Washington, which had been pressing its allies not to join.

At the time, Britain said joining the AIIB at the founding stage would "create an unrivalled opportunity for the UK and Asia to invest and grow together".

British Finance Minister George Osborne set the tone with a preparatory visit to China last month, when he courted Chinese investment into Britain and won praise from Chinese state media for having the "etiquette" not to press human rights issues.

Still, Xi's visit, the first state visit by a Chinese president since 2005, will not be without potentially awkward moments. Newly installed opposition leader Jeremy Corbyn intends to bring up the issue of human rights when he meets Xi, his official spokesman has said.

"No Glass Doors"

Xi called on Britain and other countries to avoid what he characterized as bias against Chinese companies, as Beijing supports firms in fields from high-speed rail to nuclear technology in their efforts to compete for contracts overseas.

"Competition is necessary for a business to grow, and no one will give away a market to its rivals," Xi said in comments provided in English. "We hope that such competition is benign and market-based. There should be no swing doors or glass doors which are placed as non-economic or non-market-based barriers."

One deal expected to be inked during Xi's visit is a plan for two state-owned Chinese utilities to invest in a 16 billion pound ($25 billion) nuclear power project being built by French utility EDF at Hinkley Point in southwest England.

EDF Energy's head Vincent de Rivaz has described Xi's visit as a "timely opportunity" to seal the deal.

China has ambitions to sell its own nuclear technology overseas, including in Western nations. While critics have said that Chinese government support, including cheap financing, for companies in that and other sectors could amount to unfair competition, Xi defended China's approach.

"Even under market conditions, countries support the growth of their companies in various ways, and such measures should not be all labeled as government subsidy," Xi said.

His comments were prepared by Chinese government officials, but were reviewed and approved by Xi himself, the government said.

Xi also underscored China's readiness to strengthen financial cooperation with London, which aims to be an important hub for yuan trading and offshore yuan business and is set to be the first location outside China and Hong Kong to host the issuance of Chinese central bank and finance ministry debt.

"When conditions are in place, China is ready to consider strengthening the connectivity of the financial markets of the two countries," he said.

Worries Over Economy

Xi acknowledged that the Chinese economy's slowing was a concern.

"As an economy closely linked to international markets, China cannot stay immune to the lackluster performance of the global economy. We do have concerns about the Chinese economy, and we are working hard to address them. We also worry about the sluggish world economy, which affects all countries, especially developing ones," he said.

Economists polled by Reuters expect growth to have slowed to 6.8 percent from a year earlier in the third quarter, the weakest pace since the first quarter of 2009 and below the government's target of 7 percent for the year. GDP figures are due to be published on Monday.

Still, Xi added that the slowing was normal as a part of structural adjustments, as the government seeks to wean it off an over-reliance on investment in infrastructure and housing and to develop new drivers of growth, such as the services sector and high-tech industry.

Xi said the monetary easing steps China had taken to date, as well as its adjustment to the exchange rate mechanism for the yuan in August, which was accompanied by a devaluation of the currency, had helped to defuse risks.

"Going forward, we will deepen market-oriented financial reforms according to law to cultivate an open and transparent capital market that enjoys long-term, stable and sound development," he said.

U.S. and European businesses have complained about what they see as an increasingly restrictive environment for doing business, for example with new rules on technology sales forcing firms to choose between forgoing the market and handing potentially sensitive data to Chinese authorities.

Xi said China would continue to seek to attract foreign investment, improve the rule of law to enhance the business environment, protect intellectual property rights, and promote fair competition.

Footballing Ambition

China has rattled nerves around the region and prompted concern in Western capitals about its increasingly assertive moves to push its territorial claims in the South China Sea, including construction of artificial islands.

Xi was unequivocal in his defense of China's right to develop the areas it claims as its own.

"The islands and reefs in the South China Sea are Chinese territory since ancient times. They are left to us by our ancestors. The Chinese people will not allow anyone to infringe on China's sovereignty and related rights and interests in the South China Sea," he said.

But it is not in China's interests for there to be instability in the South China Sea, he added.

"China would not want any turbulence there, still less would it be the party to stir up chaos," Xi said, adding that China would work to manage disputes via talks and ensure freedom of navigation.

On a lighter note, Xi, a football fan, highlighted the potential for further UK-China cooperation on the sport. Xi will visit the Manchester City football club on Friday, accompanied by British Prime Minister David Cameron, according to a schedule of the trip provided by Buckingham Palace.

"My greatest expectation on Chinese football is for the Chinese team to be one of the best in the world and for football to play an important role in making people stronger in body and mind," Xi said.
