China is exporting COVID-19 vaccines to 27 countries and providing vaccine aid to 53 countries in need, Chinese Foreign Ministry spokesperson Zhao Lijian said on Thursday.

"We will continue to work with other parties to promote equitable distribution of vaccines around the world and join hands with all countries to fight the pandemic," he said.

As of February 25, three Chinese companies have rolled out COVID-19 vaccines, including Sinopharm, Sinovac and CanSino, of which the first two have already received conditioned commercial approval in the country. Different than the other two, CanSino's COVID-19 vaccine is a single-shot vaccine and in the process of applying for its approval for general use.

A growing number of countries across the world have turned to Chinese COVID-19 vaccines as Western vaccine makers' production and delivery hiccups hamper the fight against the pandemic in many countries.

In February, China vowed to contribute 10 million doses of COVID-19 vaccines under the COVID-19 Vaccine Global Access (COVAX) Facility, according to Foreign Ministry.
