Language - the spoken and unspoken (nonverbal communication such as facial expressions, personal space, and hand gestures ) means of communication
Countries with more than one language often have more than one culture.
English is the most widely spoken language in the world.
Chinese is the mother tongue of the largest number of people.
English is also becoming the language of international business.
Knowledge of the local language is still beneficial, and in some cases, critical for business success.
Failing to understand the nonverbal cues of another culture can lead to communication failure.
