Over a dozen trucks loaded with 4,000 sheep from Mongolia arrived in the China-Mongolia border city of Erenhot, Inner Mongolia Autonomous Region, on Thursday. This was the first batch of 30,000 sheep donated by Mongolia in support of China's COVID-19 epidemic fight. According to a bilateral agreement, the sheep are transported to Erenhot in batches, where they are slaughtered and processed before being sent to central China's Hubei Province, the former frontier of China's epidemic fight.
