<br/>US President Barack Obama has signed into law a $7.5bn aid package for Pakistan, after fears it might impinge on Pakistani sovereignty were eased. It follows meetings between the bill's authors, Democrats John Kerry and Howard Berman, and Pakistani Foreign Minister Shah Mehmood Qureshi. The two congressmen issued a statement saying the bill set no conditions that would infringe Pakistan's sovereignty.<br/><br/>It triples non-military US aid to an annual outlay of $1.5bn for five years. Mr Qureshi's meetings with Mr Kerry and Mr Berman – the chairmen of the Senate and House foreign relations committees – came a week after he had been in Washington praising the bill. His rushed return to the US capital for further talks followed a surge of opposition to the legislation among Pakistan's military and many politicians. The Pakistani army expressed "serious concerns" about the package and said it was uneasy about "clauses impacting on national security".
