When a company buys a business in another country, it is not just acquiring assets — it is stepping into a different legal system, a different political climate, and a different set of societal expectations.

In this chapter, we explore what makes international mergers and acquisitions tick, how to spot lurking political dangers, and what you can do to protect your investment before and after the deal.
