Brooks Running is considering shifting the company’s manufacturing operations from China to Vietnam to avoid trade war tariffs, Brooks’ CEO Jim Weber said in an interview with CNBC’s “Squawk Box.”

“We’re preparing for a 25 percent tariff on our business, and that’s on top of 20 percent already on running shoes,” Weber said. “It’s really going to be upsetting for us.”

Vietnam will be a “possible” new supply chain for Brooks, Weber said, adding that the transition will likely cost “millions” of dollars.
