China has decided to donate an additional $30 million in cash to the World Health Organization to support its global fight against the novel coronavirus, an official said Thursday.

The decision announced by Chinese Foreign Ministry Spokeswoman Hua Chunying on Twitter came amid growing criticism against the global health body led by U.S. President Donald Trump.

Chunying said the donation would support WHO's fight against the global pandemic "in particular strengthening developing countries' health systems."

She also noted that Beijing had already donated $20 million to the organization on March 11.

"At this crucial moment, supporting WHO is supporting Multilateralism and Global Solidarity," Chunying tweeted.

Trump had cut U.S. financial support to the organization, criticizing its late warnings against the coronavirus pandemic that infected over 2.6 million people across the globe and killing more than 183,000.

WHO rejected the accusations and its chief Tedros Adhanom Ghebreyesus said he hoped that "the freezing of the funding will be reconsidered and that the U.S. will once again support WHO."
