Prime Minister Tony Blair will hold talks Thursday with Canadian Prime Minister Paul Martin and European Commission President Jose Manuel Barroso on terrorism and trade. The summit will take place via a video link between London, Brussels and Ottawa, said Blair's official spokesman, who speaks on condition of anonymity because he is a civil servant. With the World Trade Organization summit in Hong Kong just three weeks away, Thursday's talks will likely focus on global trade, but will also cover international terrorism and Britain's G-8 goals of tackling climate change and poverty in the developing world, the Associated Press reported.
