When the Cold War ended, governments and companies believed that stronger global economic ties would lead to greater stability. But the Ukraine war and the pandemic are pushing the world in the opposite direction and upending those ideas.

Important parts of the integrated economy are unwinding. U.S. and European officials are now using sanctions to sever major parts of the Russian economy — the 11th largest in the world — from global commerce, and hundreds of Western companies have halted operations in Russia on their own. Amid the pandemic, companies are reorganizing how they obtain their goods because of soaring costs and unpredictable delays in global supply chains.

Western officials and executives are also rethinking how they do business with China, the world’s second-largest economy, as geopolitical tensions and the Chinese Communist Party’s human rights abuses and use of advanced technology to reinforce autocratic control make corporate dealings more fraught.
