Ebola has killed more than 11,200 people in West Africa since it broke out in December 2013.
China, Africa's biggest trading partner, has sent hundreds of medical workers to Africa and contributed aid of more than $120 million to the anti-Ebola effort, after initially facing criticism for not doing enough.
Many big companies in China have invested in Africa, tapping the continent's rich vein of resources to fuel the Asian giant's economic growth over the past couple of decades, Reuters reported.
About 200 operate in West Africa, where Ebola has been at its most lethal.
