The two accused, Chen Haisheng and Li Ming, were arrested on Monday night when police started an investigation after seeing the picture online.
The duo chased and hit the wild donkey with their vehicle and when it collapsed, they killed the animal with a knife, disembowelled it and later cooked it, said Dandar, head of the Ali Forestry Public Security Bureau.
Chen and Li work for an electricity company in northwest China's Shaanxi Province, state-run Xinhua agency reported.
