(Reuters) - The chief executive of Dutch computer chip equipment supplier ASML on Wednesday said a U.S.-led campaign to restrict the company's exports to customers in China in the name of national security has become more "economically motivated" over time.

Christophe Fouquet, speaking at a Citi conference in New York, said he expects pushback against U.S.-led restrictions to grow, and at the same time that Chinese advances in chip making will be limited by restrictions that are already in place.
