"The alliance has still not responded, although objectively speaking, such interaction would raise the efficiency of efforts of the International Security Assistance Force in Afghanistan," Vitaly Churkin said at a Security Council session on Afghanistan.
The Collective Security Treaty Organization is a security grouping comprising Armenia, Belarus, Kazakhstan, Kyrgyzstan, Russia, Uzbekistan, and Tajikistan.
Churkin said Russia is concerned over increasingly frequent Afghan civilian deaths during operations carried out by the NATO-led International Security Assistance Force, and urges for measures to be taken to stop the killings.
He also said Russia is ready to continue providing economic aid to Afghanistan. He stressed that Russia is taking part in a number of projects to restore the country's energy and transport infrastructure.
The envoy also said Russia has made a significant contribution to the country's economic stabilization by writing off last August around 90% of Afghanistan's Soviet-era debt, to a total of $11.1 billion.
