The announcement of the donation was made Thursday by the Chinese Foreign Ministry's spokesperson Hua Chunying.
On her Twitter account, Hua Chunying recalled that the government donated $20 million in cash to the WHO on 11 March.
China's donation comes one week after President Donald Trump's administration announced the end of funding to the WHO.
China has decided to donate additional $30 million in cash to WHO to support its global fight against #COVID19, in particular strengthening developing countries' health systems. China already donated $20 million in cash to WHO on March 11.
