U.S. PresidentDonald Trump says in a tweet that he is working with Chinese PresidentXi Jinping to get the Chinese telecom company ZTE "back into business, fast." ZTE suspended its main operations after the U.S. Department of Commerce banned American companies from selling to the firm for seven years as punishment for ZTE breaking an agreement reached after it was caught illegally shipping U.S. goods to Iran.
