US and EU leaders have said they could launch bilateral trade talks to boost jobs and growth. At the conclusion of a White House summit, they announced a joint working group to explore how to enhance the untapped potential of transatlantic economic co-operation. The statement followed wide-ranging talks between US President Barack Obama and European Union leaders. Foreign aid and cybersecurity were also on the agenda as President Obama met EU Council President Herman Van Rompuy and European Commission President Jose Manuel Barroso yesterday. The eurozone debt crisis loomed over their talks. President Obama said after the meeting that this issue was of huge importance to the US economy. The US and EU account for around half of the world's economic output and the 27 countries of the eurozone make up the largest trading partner for the US.
