A Qatar firm that is to supply a fifth of Britain's future gas warns high prices could spark a global recession.
Economic growth is fuelling demand
Gas prices are at record levels with global demand for energy boosted by economic growth in China and India.
Faisal al-Suwaidi, head of Qatargas, warned the high prices could spark a recession in the developed world.
Qatargas is to supply up to 20% of Britain's gas starting in 2007 at the earliest, with the fuel arriving in liquid form.
The imports will come through a new terminal at Milford Haven.
Mr Al-Suwaidi said the high global prices would affect supplying nations as well as the consuming countries.
