NAIROBI, Nov. 24 (Xinhua) -- A key UN conference on south-south economic relations will be held in Kenya's capital, Nairobi, early next month, organizers said on Tuesday.

A statement from the UN office in Nairobi said the Dec. 1-3 conference whose theme is "Promotion of South-South Cooperation for Development" will bring together key leaders together to forge stronger cooperation and discuss their positions with regard to a number of pressing international concerns.

"All States of the UN system, as well as intergovernmental organizations with observer status with the UN General Assembly and UN specialized agencies and other entities of the UN system, have been invited by Secretary-General Ban Ki-Moon to participate in the conference," the statement said.

It said the meeting will consist of plenary meetings and interactive multi-sector stakeholder round tables on two sub-themes and will seek to strengthen the role of the UN system in supporting South-South and triangular cooperation.

Heads of State or Government, ministers, special representatives and other high-ranking government officials are among those expected to attend.

"Also invited are Non-Governmental Organizations and public and private sector development partners of the United Nations. UNDP Administrator Helen Clark is one of the high-level UN officials who will attend the Conference," the statement said.

The conference is the outcome of a UN decision to convene such a conference on the 30th anniversary of the adoption of the Buenos Aires Plan of Action for Promoting and Implementing Technical Cooperation among developing countries (TCDC).

The General Assembly has described South-South cooperation as an important element of international cooperation for development, which offers viable opportunities for developing countries in their individual and collective pursuits of sustained economic growth and sustainable development, and emphasized that South-South cooperation is not a substitute for, but is complementary to, North-South cooperation.
