The Shanghai Cooperation Organization (SCO) on Friday reiterated its support for the United Nations to play a leading role in international mediation efforts for Afghanistan.

The continuous deterioration of the situation in Afghanistan as well as terrorism, drug trafficking and transnational organized crime that originate in the country still pose "serious threats" to the region, said a declaration released at the end of an SCO summit in the Uzbek capital.

Peace and stability in Afghanistan is conducive to the region's continued social and economic development, the declaration said.

The SCO member states believed "military means alone" cannot solve the country's problems, the declaration said.

The SCO called on the international community to intensify the fight against all sections of drug production and circulation in Afghanistan.

The SCO member states would like to coordinate with other international and regional institutions on the drug issue and call on the International Security Assistance Force to cooperate with SCO members in combating drugs, the declaration said.

The declaration said the organization supports its member states in working together with international institutions and other parties to take part in the economic reconstruction programs in Afghanistan.
