ISLAMABAD While the Quadrilateral Summit appears to be a significant step towards redefining the patterns of regional cooperation, the longstanding core issues between the major stakeholders are yet to seek redressal. Although the event is evaluated on high notes and the heads of all the four participant states, Pakistan, Russia, Afghanistan and Tajikistan, talked 'big for striving to enhance regional cooperation, the traditional constraints that hinder the way to regional development were evident during the summit. The US influence which has had always dominated Pak-Afghan relations manifested itself when the bilateral meet-up sessions held between President Karzai and Zardari ended up only on tall rhetoric and ages-old stereotypical 'brotherly promises instead of bringing about anything worthy. Karzai conveniently dodged any serious discussions on anti-narcotics control other than making routine pledges. Likewise, despite the seriousness shown from Russian side, talks on the much-delayed Pak-Russia anti-drug trafficking agreement could not proceed any further let alone signing the agreement. Although Russian President Dmitry Medvedev had openly expressed reservations about the unlawful transportation of Afghan drugs into Russia and the neighbouring states, the fact that no breakthrough could take place to eradicate this menace not only characterises Pakistans submissive posture towards US, it, at the same time, reflects US support for Hamid Karzai to foil anti-narcotics efforts in the wake of lucratively pervasive black market in Afghanistan that earns billions of dollars each year, 'mutually benefiting Afghan Government and US backed powerful lobby in NATO. In addition, the fate of CASE-1000 project of transporting power energy from Tajikistan to Afghanistan and Pakistan might fall victim to Pakistans criminally negligent bureaucracy that has already thrown Pak-Iran mega power project of 1,000 megawatts into abeyance courtesy the insatiable money mongering motives of Ministry of Water and Power. Nevertheless, the Quadrilateral Summit marks an important reassertion of Russias role in this region to move towards the Soviet era cooperation in the Central Asian-Afghanistan region. Pakistans participation was also one small effort to move out of the US grip, in terms of Afghan policy. Apart from CASE-1000, the proposed establishing of Salang tunnel linking north and south Afghanistan and other cooperative projects in the energy sector bring worthy achievements to Quadrilateral Summits credit. For Pakistan, this Quadrilateral Summit and the interaction with the Russian leadership can be of significance only if Pakistani leadership sustains a follow-up in a substantive manner rather than just paying lip service to summit diplomacy; after all, it allows Pakistan a foot in the door of cooperation with Russia with whom India has historically close strategic ties. The summit was a signal that the US and NATO will be increasingly challenged not only by their own failures in Afghanistan, but also by the resurgent ambitions of Russia in Central Asia and Afghanistan. It is imperative for Pakistan to remove its Washington-focused blinkers before it is marginalised in its own region.
