In terms of FDI, Foreign Direct Investment, acquisition is taking over all or a majority stake in a company in a foreign land, as a hypothetical instance, Tesco in England taking the majority stake in Whole Foods in America. This is quite different from FDI that is greenfield. Greenfield FDI is very often a company in a developed country investing in building facilities in a developing country (this is very different from what are commonly called "start-ups") to take advantage of tax breaks and other incentives. Which form of FDI a multinational company might choose depends upon their expansion objectives, thus, hypothetically, the objective for diversification might lead toward FDI acquisition investment, while the objective for cost-cutting might lead to FDI greenfield investment. Bear in mind, while acquisition and "start-up" apply to homeland company expansion, greenfield is strictly applicable to Foreign Direct Investments, and acquisition may be a type of Foreign Direct Investment.
