"Going forward, I am of the view that China and Asean must continue working together in the fight against and overcoming Covid-19 pandemic so as to sustain socio-economic activities and people's livelihood," Hun Sen said.
He added that the fight against this global pandemic requires solidarity, trust, joint planning as well as action in a prudent manner under a multilateral mechanism with respect for international law and sovereignty of each country.
"In addition, China-Asean must continue promoting cooperation in all sectors, especially finance and trade, in order to accelerate the socio-economic recovery in the aftermath of the Covid-19 crisis through widening the openness of market and flows of free trade, as well as facilitation of investment flows," he said.
Meanwhile, Hun Sen extended his deep gratitude to the government and the people of China for the assistance to Cambodia through all forms of supports, including Covid-19 treatment techniques, medical equipment, and COVID-19 vaccines.
"At the same time, I highly commend the government and the people of China for the active participation and its leading role in the fight against the COVID-19 at the global level, via the production and distribution of vaccines, provision of medical equipment as well as experience-sharing on prevention, care and treatment for the COVID-19 patients," he said.
