China is willing to play a constructive role in Sri Lanka's economic and social stability and development, Chinese Premier Li Keqiang said on Friday during a phone call with Sri Lankan Prime Minister Mahinda Rajapaksa.

The South Asian country has been facing political instability and a severe economic crisis, with inflation at record high and shortages in fuel and other essential supplies.

Li said that China, within its capacity, is ready to provide emergency aid to Sri Lanka to help with its people's livelihood.

He said in the principle of non-interference in others' internal affairs and respect for Sri Lanka's willingness, China stands ready to play a constructive role in its economic and social stability and development.

The Chinese premier also pledged that China will boost pragmatic cooperation with Sri Lanka in various fields, including negotiation and signing of a free trade agreement (FTA).

Rajapaksa thanked China for providing emergency humanitarian aid, and appreciated the Chinese side's support for his country at a time of difficulties.

Sri Lanka is ready to strengthen cooperation with China in finance, trade, tourism and others, and promote the negotiation process of the FTA.
