Colombo, Nov 18 (ANI): As the Commonwealth Heads of Government Meeting (CHOGM) came to a close, member countries agreed in unison to support small and less developed nations in the pool, which forms one-fifth of global trade. The summit took place in the island nation under the shadow of allegations of abuse by the Sri Lankan government four years after a civil war against Tamil separatists ended. President of Sri Lanka, Mahinda Rajapaksa, said that the member countries had also agreed to tap the potential of intra-Commonwealth trade and investment.
