UN Secretary-General Ban Ki- moon said here Wednesday that 'Afghanistan will remain one of our main priorities in 2010,' and the relations between Afghanistan and its international partners 'must be reevaluated.' The secretary-general made the statement as he was speaking to an open Security Council meeting on Afghanistan, the first open council session this year. In his report to the 15-nation Security Council on Monday, Ban cautioned against an 'irreversible' deterioration in security and politics in Afghanistan and called for a new UN-led civilian effort to help build the war-torn nation. 'There can be no doubt that Afghanistan will remain one of our priorities in 2010,' Ban told the Security Council meeting. 'Last year was another extremely challenging period for Afghanistan and for international efforts to assist the government and its people,' he said. 'Difficult elections ... deteriorating security ... doubts about the current strategies of both the government and international community.' 'All combined to produce further violence and uncertainty for a country facing immense challenges,' he said. Ban, in his new report, warned against the twin effects of deteriorating security and the fraud-plagued presidential elections in August 2009, both have contributed to the Afghan government's inability to deliver basic services, which is fueling the expansion of the Taliban insurgency. 'Efforts by the Taliban and insurgents to prevent people from participating in the electoral process has also destroyed social structures and traditional security mechanisms,' he said. 'This insecurity remains the single biggest impediment to progress.' 'Afghanistan is at a critical juncture,' he said. 'All key players -- Afghan and international -- have drawn important lessons from controversial experiences and missed opportunities.' 'I appeal to both the Afghan government and the international community to make the best possible use of the next few months,' Ban said. 'AT the same time, the relations between Afghanistan and its international partners must be reevaluated,' he said.
