Chinese officials today announced that China has sold nearly 4 billion masks to other countries since March between Covid-19.

Although Covid-19 is leveling off in China, Beijing still encourages factories to increase production of medical devices as the epidemic continues to complicate globally, leaving more than 1.2 million people infected, of which more than 60,000 died.

China has exported 3.86 billion masks, 37.5 million protective clothing, 16,000 breathing machines and 2.84 million nCoV test kits since March 1, with orders from more than 50 countries, officials said. Jin Hai customs today said and added that the value of Chinese medical supplies exported was estimated at approximately US $ 1.4 billion.

However, a number of countries, such as the Netherlands, the Philippines, Croatia, Turkey and Spain, have complained about substandard or faulty medical products originating from China.

The Netherlands last week recalled 600,000 masks in a shipment of 1.3 million units from China for failing to meet quality standards. Beijing countered that the manufacturer "made it clear that this is not a medical mask."

Spain last week also rejected thousands of quick test kits from an unlicensed Chinese company after finding them unreliable.

On April 5, China responded to media reports saying its medical supplies were faulty, insisting they were "not completely reflective of reality".

"The reality is that there are many influencing factors, such as China having different standards and other usage habits. Improper use can also lead to quality doubts," Jiang Fan said. from the Ministry of Commerce of China, said.

Beijing earlier this week tightened regulations on exported medical equipment related to nCoV, requiring products to meet both domestic licensing standards and standards in the country of destination.
