MOSCOW, October 27 (RIA Novosti) - The prime ministers of Eurasec, an economic alliance of six ex-Soviet republics, will meet in Moscow Friday to discuss forming a customs union.

The Eurasian Economic Community's secretary general, Grigory Rapota, said: "Draft documents on forming the legal framework for the customs union are ready, and will be presented at the Eurasec Interstate Council prime ministers' meeting in Moscow."

The meeting will be attended by the premiers of Russia, Kazakhstan, Kyrgyzstan, Tajikistan, and Belarus, and the deputy prime minister of Uzbekistan, which joined the post-Soviet alliance in early 2006.

The customs union envisions no duties or taxes for imports or exports on the organization's territory.

Initially, only three Eurasec members - Russia, Kazakhstan and Belarus - will join the customs union, as they have already harmonized most of the necessary documents.

At Friday's meeting, the 17th of its kind, the heads of government will discuss changes and additions to draft lists of goods and technology subject to export controls, and changes to Eurasec intergovernmental programs.

The prime ministers are also expected to address other issues, including the use of water and energy resources in Central Asia, and the Eurasec budget.
