LONDON: US President Donald Trump's state visit to the UK has delivered pledges from US tech giants to invest tens of billions of dollars in the AI sector.
The UK and US governments, meanwhile, agreed on co-operation over nuclear and space technology as part of a "Tech Prosperity Deal", and British pharmaceutical group GSK pledged investment in the United States.
The single biggest planned investment comes from US private equity firm Blackstone, which said it would plough £90 billion ($123 billion) into UK assets over the next decade.
Below is a list of the main deals, including some £150 billion of inward investment from US companies.
Big tech
Microsoft's "largest ever commitment to the UK" comprises a $30-billion investment over four years, half of which will be spent on cloud computing and artificial intelligence infrastructure.
It includes plans to build Britain's largest supercomputer.
"We're committed to creating new opportunities for people and businesses on both sides of the Atlantic, and to ensuring America remains a trusted and reliable tech partner for the United Kingdom," said Microsoft chief executive Satya Nadella.
"That is why we are doubling down on our investment in the UK."
Google plans UK investment of £5 billion over the next two years to power its AI drive, help "fortify cybersecurity" and create 8,250 jobs annually.
Nvidia, Stargate UK
British firm Nscale has partnered with ChatGPT maker OpenAI and chip giant Nvidia to establish a UK version of Stargate -- a large-scale AI infrastructure initiative.
The government stated that the project aims to "develop a platform designed to deploy OpenAI's technology on sovereign infrastructure in the UK."
Working alongside UK firms, Nvidia pledged to deploy a total of 120,000 advanced GPU chips across the country, representing its biggest ever rollout in Europe.
GSK
British pharmaceutical group GSK has announced it will invest $30 billion in the United States over the next five years, as drugmakers face pressure from the Trump administration to relocate production to the country.
GSK will expand its research and development investments and production capacities, the company said, including a $1.2 billion plan to build a biologics factory in Pennsylvania for the development of respiratory and cancer treatments.
"This week's state visit brings together two countries that have led the world in science and healthcare innovation," GSK chief Emma Walmsley said in a statement.
Blackstone
The group gave no details of the nature of its planned investments, which comes after its announcement last year to invest £10 billion in an AI data centre in northern England.
Bank of America, BlackRock, Citi Group, PayPal and S&P Global are together investing around £1.75 billion in their UK operations.
Government partnerships
Britain and the United States plan to speed up the development of new nuclear power projects.
"This golden age of nuclear is central to the government's mission to build more clean homegrown power to ensure energy security," the UK government said.
The two countries plan to "drive AI-powered healthcare solutions in areas such as precision medicine and chronic disease".
The UK and U.S. plan also to partner over "revolutionary quantum computers and speed up the deployment of this technology across areas like healthcare, defence and finance".
NASA and the UK Space Agency intend to develop AI models to support science and exploration missions.
