China wealth fund buys nearly 9% of Thames Water

China Investment Corporation (CIC), the country's sovereign wealth fund, has bought 8.68% of the company behind UK utility group Thames Water.

It is the fund's first major share purchase in the UK, after Chancellor George Osborne visited China this week.

Thames Water is owned by Kemble Water, a consortium of investors led by Australian bank Macquarie.

CIC was set up in 2007 to invest some of China's huge $3.18tn (£2tn) in foreign exchange reserves.

In a one-sentence statement on its website, CIC said it bought the stake through a wholly-owned subsidiary. No purchase price was disclosed.

Thames Water, acquired by Kemble in 2006, is the UK's largest water and sewerage company, serving about 14 million customers.

CIC chairman Lou Jiwei had said recently that his company was interested in investing in European and US infrastructure.

Speaking about the deal, the Chancellor said: "This is a significant step by China. It is a vote of confidence in Britain as a place to invest and do business.

"This investment is good news for both the British and Chinese economies."

Mr Osborne met China's Vice-Premier Wang Qishan and the heads of CIC and the ICBC bank on Tuesday.

The chancellor also announced that Britain had agreed to work with Hong Kong to develop the City of London as a major offshore centre of trade in China's currency, the yuan.

The government has been looking at ways to support greater private sector and foreign investment in infrastructure.

Speaking to the BBC Today programme, former Trade Minister Lord Digby Jones said: "It is good news because in Britain, and the water companies know this, needs constant repairs , so more funds in to help that when it's not a drain on the public purse has to be right."

Mr Osborne's meetings in Beijing earlier this week discussed potential Chinese interest in a number of projects in the plan.

In August, Northumbrian Water agreed to a £2.4 billion takeover by a Hong Kong-based investment firm led by Asian billionaire Li Ka-shing.

In December, the Abu Dhabi Investment Authority, another huge sovereign wealth fund, bought 9.9% of Kemble for an undisclosed price.

Thames Water supplies households in London, Berkshire, Buckinghamshire, Gloucestershire, Kent, Oxfordshire, Surrey and Wiltshire.

In the last 10 years, Ferrovial of Spain has bought BAA, the operator of Heathrow and Stansted airports, Germany's RWE has acquired npower, and Australian bank Macquarie has taken control of car parks by buying NCP.
