Millî Reasürans T.A.Ş., representing Turkish delegation in the field of insurance in the "Regional Cooperation for Development (RCD)" Organization as per the agreement signed among Turkey, Iran and Pakistan in 1964, has played a very active role in forming the RCD Fire, Marine, Accident and Engineering reinsurance pools as well as the RCD Insurance Center.

As of the 1st January 1975 these pools were integrated under one pool and the management of the same was entrusted to the Millî Re. The name "Regional Cooperation for Development (RCD)" was changed to "Economical Cooperation Organization (ECO)" in the meeting of the Organization dated 6th-7th July 1985, so the name of the Pool to ECO Reinsurance Pool.

Later, as per the decision taken by the IIIrd Summit which gathered the presidents of three countries in Islamabad on 11th-15th March 1995, the ECO Pool stopped underwriting new business as at 31st December, 1995 as "insurance" section of the Organization was shifted to Pakistan, "transportation" to Iran and "banking" to Turkey.

The Pool's premium income at the end of the first year of activities, i.e. 1975 being US Dollars 2.456.331, was of US Dollars 13.746.603 when the pool stopped underwriting new business as at 31st December, 1995 and after a thirteen years' run off it has reached US Dollars 20.099.585.
