China in April took steps that resulted in slower exports of medical equipment, primarily due to concerns over quality raised by European governments.
On April 10, China's customs administration announced that it would inspect every shipment of medical equipment for compliance with quality standards, resulting in processing delays. Authorities announced further measures later in the month to manage the flow of goods.
Other factors contributing to delays included a surge in demand for personal protective equipment in China and abroad and a lack of air cargo capacity.
