David Cameron has hailed a "historic" global trade deal which he said could be worth £1 billion a year to British businesses.
The World Trade Organisation (WTO) secured a deal to lower barriers and speed up customs procedures after overcoming late objections from India and Cuba.
"I am delighted that we have secured an impressive global deal worth over £1 billion a year to British businesses and £70 billion globally. This deal will help boost our exports, meaning that UK companies can grow and employ more people.
"If just 100,000 small businesses either start exporting or spread to new markets over the next five years, this would generate an extra £30 billion for the UK economy and create 100,000 new jobs.
"By slashing barriers to trade, this deal will also provide a lifeline to the world's poorest people."Helping developing countries to grow is not only the right thing to do, but it also increases potential markets for us all.
"So this really is win-win and the World Trade Organisation is to be commended for this historic deal."
The WTO Trade talks, which had opened on Tuesday, nearly came unstuck at the last minute. At the eleventh hour, Cuba suddenly refused to accept a deal that would not help pry open the US embargo of the Caribbean island, forcing negotiations to drag into Saturday morning.

The announcement of small business grants for high speed broadband coincides with the Small Business Saturday initiative promoting the firms Mr Cameron described as the "lifeblood of our economy".
– Prime Minister David Cameron
Up to £3,000 of broadband vouchers for small business in these cities is not only a massive boost for growth in the UK, but also has the potential to bring China to Cardiff, Brazil to Bristol and the Emirates to Edinburgh in an increased export market.
To do that we are working on a complete overhaul of the UK's infrastructure; high speed broadband is a vital part of this. And on Small Business Saturday, what better way to support small businesses - the lifeblood of our economy - than to help kit them out for the 21st century.
Small businesses in 10 cities across the UK will be able to apply for grants to install high speed broadband as part of a £100 million scheme to boost growth and exports.
Firms in Belfast, Salford, Portsmouth, Cardiff, Derby, Bristol, Edinburgh, Newport, London and Manchester will be able to access grants worth up to £3,000 to improve their connections, with the scheme due to be extended to 12 more cities next year.
Prime Minister David Cameron said he wanted to give firms the ability to set up or locate anywhere in the UK.

The company said that means the average variable dual fuel bill will go up by £48, electricity only prices will increase by 3.7% or £20, and gas only bills will climb by 4.6% or £37.
