Doing Business In China
China has a relationship-driven business environment. You should develop rapport with the layers of Chinese players that you will need to work with or choose a partner who already has cultivated them.
Keep in mind that although the people in China that you will be working with will speak English, you should communicate via email whenever possible to avoid misunderstandings.
Also, note that China will be operating about a half day ahead, so early morning and late night calls are the only intersecting times. This is another reason to use email. The Chinese holidays are different. Consider this in your timelines and communications.
