International Security

The rapidly changing strategic environment of the twenty-first century challenges old definitions of what security means, who is or should be involved, and what role national governments play.

Great power competition is playing out in a new way. Confrontation will not be through massed armies in Europe or nuclear arsenals on trigger alert but will occur more indirectly and more often than not in non-military domains. Strategic rivalry is taking place in the pursuit of technological innovation, in disputes below the threshold of full-scale war, and in trade, investment, industrial, and economic competition.

Geo-economics, which can be defined as the use of economic instruments to promote and defend national interests and to produce beneficial geopolitical results or as the effects of other nations’ economic actions on a country’s geopolitical goals, is arguably the primary arena of this renewed competition.


A multi-campus, multi-year project led by IGCC focuses on the technological, economic, and domestic dynamics of the renewed great powers competition between the United States, China, and Russia.

Strategic competition increasingly takes place across domains. The most obvious are the military-civilian divide, the role of the state versus private actors in foreign investment, and confrontations below the threshold of war. IGCC is exploring these dynamics through a number of projects.
