The German health minister regretted the US official notice of withdrawal from WHO, calling the move a 'setback for international cooperation.'
Jens Spahn tweeted that more global cooperation, not less, is needed to fight pandemics, AP reported.
"European states will initiate #WHO reforms," he noted.
Juergen Hardt, a foreign policy spokesperson for German Chancellor's center-right coalition, said the US withdrawal damages US and Western strategic interests just as China has been taking a greater role in international institutions.
"As the biggest contributor so far, the U.S. leaves a big vacuum," Hardt added. "It is foreseeable that China above all will try to fill this vacuum itself. That will further complicate necessary reforms in the organization."
