Comrade means "friend", "colleague", or "ally". The word comes from the French camarade.
In Chinese, the word for Comrade literally translated means, "people with the same spirit, goal, ambition, etc." It was first introduced in the political sense by Sun Yat-sen to refer to his followers. The term was promoted most actively by the Communist Party of China during its struggle for power. It was used both as a noun and as a title for effectively anyone in China after the People's Republic of China was founded.
