"The manufacturing industry in the US is highly developed. We can't fall behind," said Fan Shouyun, vice-general manager of Giti Tire, at the automation fair. Giti Tire has been gradually updating its five plants in China.

O'Reilly said it's easier for Chinese manufactures to update their systems in comparison to many Western plants, which are 30 or 50 years old. "Plants in China are relatively new, so their infrastructure is contemporary," he said. "They'll catch up very fast, and in fact, in some areas they may be ahead."
