"Russia and Afghanistan must engage more closely with one another economically, politically and strategically," he added.
"A stronger and more affirmative Russia is a guarantor of stability and safety in Afghanistan," Karzai said at the 5th Moscow conference on international security.
Strengthening of Russian positions in Central Asia will contribute to the stability in the region and Afghanistan, Karzai said.
"When Russia was strong, Afghanistan was stable. That’s why today – that’s my very clear opinion – that stronger Russia, resurgent Russia in our region engaged with Afghanistan politically and economically, training Afghan forces, giving us the knowledge they have will bring stability back to Afghanistan and vice versa to Russia. So that should we do today and that I’m working on," Karzai told the RT broadcaster.
Afghanistan is in a state of political and social turmoil, with the long-standing Taliban insurgency continuing in the country, while other extremist groups have expanded their activities there also.
