A prominent feature of Japan's capitalism consists of families of companies called keiretsu that are linked by crossholdings of stock shares, intra-group financing, and certain coordinating mechanisms. Two types of keiretsu exist: large horizontally organized industrial conglomerates, such as Mitsubishi, Mitsui, and Sumitomo, and vertically integrated manufacturers, such as Toyota, Nippon Steel, and Matsushita Electric. They have become a contentious issue in U.S. trade negotiations with Japan for several reasons.

Discussions in Japan in May 1992 related to potential agreements at the September 1992 Russian-Japanese summit were keyed to the central question, Will the barriers to significant commercial cooperation involving Russia, Japan and the United States in Russian Siberia be removed? [1] From these discussions among key Japanese industrialists, bankers, government officials and academics who influence policy, came a tentative "yes", if four conditions are met. A positive outcome would thus seem more likely than at any previous time. Such an outcome would likely promote profitable trade and investment, creating jobs in U.S. enterprises and serve as a vehicle for mutually beneficial U.S.-Japanese cooperation.
