London, Feb 9: Prime Minister Gordon Brown has asked the British youths to acquire "new training" to head off challenges from fast-growing economies like India and China for the world's leading jobs.

"Good global jobs are going to be created, the opportunities for social mobility are there in a greater way than at any time since 1945," he said addressing British and German academics at the International Institute for Strategic Studies here yesterday.

"But the young people needed new training if Britain is to head off the challenge from China, India and other fast-growing economies for the world's leading jobs."

The UK's big challenges include security, climate change and dealing with the power of the internet, but helping everyone to "unlock their potential to the full" is key, he said.

The Prime Minister called on Britons to seize a larger share of the world's top jobs, promising a surge in employment training and education.

"We used to talk about national economies in terms of there being limited room at the top and therefore the opportunity for social mobility was itself limited. In a global economy there's no limit to the national room at the top.

"We can build in our countries a higher aspiration culture. The opportunity revolution is one that is unlocking all of the potential of all of the people," Brown said.

His speech and question and answer session coincided with the publication of a major new report into the key long-term strategic challenges for the country.

The report, published by the Strategy Unit in the Cabinet Office, is the most in-depth analysis of future challenges yet produced by government, covering the full range of issues from emerging trends in economic globalisation to social mobility and climate change.

The report noted that the country is well placed to address the crucial issues it faces over the next 10 to 15 years.

It concluded that promoting the skills and talents of the people of Britain and improving opportunities for all people, from early years through to adulthood will be crucial in responding successfully to the competitive pressures arising from global changes.

The report said industrial economies should give up the illusion that they can compete with developing economies to provide cheap, unskilled workers.

Brown said he feared some countries, including the United States are guilty of creeping protectionism - attempting to safeguard declining industries rather than train workers in new skills.
