Final answer:
A cross-border strategic alliance between U.S. company GeoTech and South Korean company TreVonix is when both companies share resources to gain a competitive advantage while remaining separate entities.
Step-by-step explanation:
When GeoTech, a U.S. company, and TreVonix, a South Korean based company, combine some of their resources to create a competitive advantage, this is known as a cross-border strategic alliance. This type of business arrangement involves the sharing of resources, technology, knowledge, and/or operational aspects to gain mutual benefits without merging into a single entity or one acquiring the other. In contrast to an international acquisition where one company takes over another, or an international merger where two companies combine to form one, a strategic alliance allows both companies to remain independent while pursuing common strategies. The main idea behind such alliances is to leverage each other's strengths to expand business opportunities and competitiveness in the global market.
