BRUSSELS (AFP) World powers told Pakistan that post-flood aid was part of a two-way deal on reform Friday, as Islamabad also offered to lend a hand to regional peace by facilitating Afghan-Taliban talks. After US Secretary of State Hillary Clinton demanded Pakistans affluent and elite be made to pay through tax changes, ministers attending a major aid meeting on Pakistan also insisted there would be no gain without some pain. For Pakistan to become more stable, German Foreign Minister Guido Westerwelle said, you can harvest as much money as you want, it wont be enough at the end of the day if there is no reform. An adjustment in the equilibrium between rich and poor in Pakistan was fundamental, he said. The meeting of the Friends of Democratic Pakistan came as the World Bank and Asian Development Bank estimated damages for Pakistans devastating floods since July at 9.7 billion dollars - almost twice the amount of its 2005 earthquake. British Foreign Secretary William Hague, who said London had already ploughed some 134 million pounds (215 million dollars) of aid, also underlined that there are necessary reforms in Pakistan and they should include a widening of the tax base. But he said Pakistan Foreign Minister Shah Mahmood Qureshi had stressed in the meeting that the government of Pakistan is fully cognizant of what they need to do. An EU source had warned before the talks concluded that backers were not signing any blank cheques. Its a two-way street, the source added, indicating EU foreign affairs chief Catherine Ashtons view that unprecedented support cannot be expected without profound changes in the way Pakistan runs its economy. We must make sure where the money goes, said one diplomat. We expect clear commitments. The floods affected 21 million people - with 12 million in need of emergency help by UN estimates. To date the United States and the EU have provided around 450 million dollars each in aid to Pakistan. Europe has also offered a major trade boost, proposing to lift duties on 75 imports as part of an aid-linked package. But the three-year suspension of duties still requires a waiver from the World Trade Organisation.
