SAO PAULO, Sept 16 (Reuters) - U.S. Trade Representative Ron Kirk said on Wednesday world economies need to stay on alert to prevent protectionism from hurting a nascent global recovery.
The world needs trade policies that open opportunities and markets, not shut them down, Kirk said at a speech to business leaders in Sao Paulo, Brazil's largest city and financial hub.
Kirk added that the U.S. and Brazilian governments should work to deepen trade relations between the two countries. (Reporting by Luciana Lopez, Writing by Elzio Barreto)
