Timothy Stratford, chair of the American Chamber of Commerce in China, played down the likelihood of a substantial deal. Despite Xi’s trade-fair talk and China’s promises to buy American agricultural products, China did not appear to be offering fixes to long-standing U.S. complaints, such as Beijing’s subsidies for certain businesses, Stratford said.“The more I’m hearing from the Chinese, the more I hear ‘we’re actually doubling down on the economic model, we’re not going to change our state intervention in key industries,’ ” he said. “China is trying to welcome foreign investments and imports and doing it in very targeted ways. That doesn’t necessarily fix the systemic problems.”
