Moves by Chancellor George Osborne to encourage Chinese involvement in the HS2 high speed rail project could pave the way for foreign investment into key Scottish infrastructure projects, according to an infrastructure and projects lawyer.

The Chancellor spent much of last week in China to try and attract investors there to bid for seven contracts worth £11.8 billion in total covering the first phase of HS2, between London and Birmingham.

Michael Watson from Pinsent Masons said the visit could also have a knock-on impact for projects north of the Border such as road upgrading and connecting offshore wind farms to the grid but only if Scotland is able to present an attractive investment proposition for the Chinese.

He said success in getting the cash-rich Chinese to support energy, transport and manufacturing projects, depended on offering up schemes which are large enough in scale and which are at an advanced planning stage.

“The Chinese tend to look for fairly substantial transactions to invest in, so they can deploy significant amounts of capital and create openings for their supply chain, technology and manpower to help build these assets,” Watson told The Scotsman.

A report by the law firm and the Centre for Economics and Business Research (CEBR), published last year, had suggested that China is set to invest £105 billion into UK infrastructure by 2025 with the energy, real estate and transport sectors the leading recipients.

“There is no reason why Scotland should not get its fair share,” added Watson. “Indeed the current turmoil in the domestic Chinese markets create further opportunities for Scotland and the UK – where Chinese investors can turn to, seeking more stable and predictable returns in infrastructure investments.”

Watson said he was upbeat about the combined efforts of the Scottish Government, Scottish Futures Trust and Transport Scotland to attract overseas investors in large infrastructure projects.

He said: “There has been a concerted effort from Scotland to attract investment from China and this could be a game-changer for Scottish infrastructure, but only if we can provide suitable projects of the scale and appropriate level of readiness which would appeal to investors.

“In order to do that we have to have ‘investable’ projects and that means taking these schemes to a stage of development where planning, structure and consent is in place. The key is to have projects which are visible, well developed and ready to be invested in, because we are competing in an extremely competitive global market and the Chinese and other overseas investors have a wealth of options on where to put their money.”

Projects of sufficient scale which could interest Chinese investors, according to Watson, include the A9 Perth to Inverness dualling project and rail electrification programmes.

In the energy sector, updating ageing North Sea infrastructure and onshore and offshore power transmission and generation initiatives are other billion pound projects which may appeal.

“Scotland has a stable regulatory and political environment compared to most countries and relative to other parts of the UK it has had a more positive story to tell regarding infrastructure investment,” added Watson.
