I found this TEDx talk from Valarie Hoeks about the intricacies and beauties of Chinese culture to be really insightful. In particular, she mentions the importance of learning a language, building relationships, and understanding historical worldviews in order to better understand a culture.
I spent over a year learning a new language and have found it to be invaluable in understanding how people in a different context think, as well as act. Book a flight to a new country and leave English behind. Make some friends over coffee or tea. Visit religious sites and cemeteries. See how it helps you in your international business.
