LONDON - British Prime Minister Gordon Brown on Wednesday unveiled a new strategy for Afghanistan and Pakistan and said he would continue work on a new concordat on strengthening co-operation between Pakistan and the UK when President Asif Ali Zardari visits Britain next month. Stating that Pakistan must be a part of a solution to Afghanistans problems, Brown pledged 665m pounds over the next four years to help Islamabad with counter-terrorism operations as well as education and economic assistance. During his speech in the House of Commons, Brown said that in Pakistan, the focus would be on supporting education and development to prevent young people falling under the sway of violent and extremist ideologies while at the same time helping the security forces regain control of the border areas. In Pakistan, he said, much of Britains 665-million-pound aid programme for the next four years - including 125m pounds of education spending - would be refocused on the border areas. At the same time, he said, senior UK and Pakistani military, intelligence and diplomatic teams would meet on a more regular basis in an enhanced strategic dialogue. Closer co-operation would be reinforced through a 10 million pounds counter-terrorism capacity-building programme with the Pakistani police and security services. Gordon Brown, who visited Afghanistan and Pakistan earlier this week, said the lawless borderlands between the two countries are a crucible of global terrorism which ultimately threaten the security of the UK. He echoed US President Barack Obama, who warned that extremism is a cancer that is killing Pakistan from within. He described security in the mountainous borderlands between the two countries -Pakistan and Afghanistan - as the greatest priority for the international community. They are the crucible for global terrorism, they are the breeding ground for international terrorists, they are the source of a chain of terror that links the mountains of Afghanistan and Pakistan to the streets of Britain, he said. The British PM said in Afghanistan, Britains aim was to build up the police and army to ensure that the countrys democratic government was strong enough to withstand and overcome the terrorist threat. The goal would be to achieve a district-by-district, province-by-province handover to Afghan control, he added. Agencies add: Of 665 million pounds, 125m pounds will be earmarked for supporting education projects in the border areas in an effort to stop the spread of extremism, he said, adding that one of the primary aims of UK support would be to stop young people falling under the sway of violent extremists. He said efforts to counter extremism must be concentrated on those areas where Al-Qaeda and the Taliban operate with impunity. On Afghanistan, Brown said Britain is to boost its troops in Afghanistan to 9,000 to help the country through upcoming elections. The British Premier underlined the threat from Al-Qaeda and its allies in both countries. He described security in the mountainous borderlands between the two countries as the greatest priority for the international community. It has become increasingly clear over the last year just how crucial Pakistan and its border area with Afghanistan has become both for stability in Afghanistan and to our national security at home, he further said. The British forces in Afghanistan would return to an enduring presence of 8,300 next year, Defence Secretary John Hutton said in a statement issued at the same time as Browns announcement in the House of Commons. These units will provide important additional capabilities for UK forces in Afghanistan. The reinforcement of two infantry companies will enable us to provide extra security during the Afghan elections, he said. Brown said that in talks with Zardari they agreed that in the border areas, there must be long-term good governance and economic development to underpin progress on security. We agreed on enhanced strategic dialogue, to bring together our senior diplomatic, military and intelligence teams on a more regular basis.
