Singh in the reply said that the devastating effect of terrorism is no longer unknown to the world after 9/11, and the world community had recognized that terrorism constitutes a very important threat to all civilized societies in the world.
"We believe that Pakistan should be as serious in tackling terrorism on its western border as on the eastern borders. I sincerely hope that the world community would use its good offices to promote this," said Singh.
The two in his meeting also had emphasized that India and Britain should constitute India-UK CEO Forum and India-UK Infrastructure Group besides doubling the quantum of trade in the next five years.
"Britain looks forward to an early conclusion of India-EU trade agreement," said Cameron.
