General Motors formed several strategic alliances in Asia to gain access to new technologies and lower production costs. This included joint ventures with Toyota and Isuzu, equity partnerships with Suzuki and Nissan, and taking management control of Daewoo. GM also partnered with components suppliers in Japan through joint ventures and equity stakes. However, GM's Asian partners often benefited more from the partnerships by using GM's investments and knowledge to later compete against the company. This contributed to GM's declining market share in the US from over 40% in the late 1970s to under 30% by the late 1980s. To address this, GM needs to consider more centralized control, effective ownership stakes, or decentralized relationships to better manage partnerships
