Rio Tinto chair: Geopolitical risk must move beyond the 'after-dinner speaker

Dominic Barton, strategic counsellor to Eurasia Group and chair of Rio Tinto, says companies must integrate geopolitical risk into core business operations rather than treating it as a side concern. Speaking after US President Donald Trump imposed 50% tariffs on some Canadian goods, Barton noted the breakdown of assumptions about international institutions and free trade. Barton, a former McKinsey leader and Canadian ambassador to China, argues CEOs need to spend more time understanding foreign governments. He says geopolitics should inform decisions about balance sheets, debt levels, supply chain security, and data management. Rio Tinto has adjusted its approach to China, significantly increasing purchases of Chinese equipment. "It's more expensive than some of the traditional Western suppliers. But it's better," Barton said.
