The United States and China on Friday said they made progress in talks aimed at defusing a nearly 16-month-long trade war that has harmed the global economy, and U.S. officials said a deal could be signed this month.

The Chinese Commerce Ministry on Friday said the world's two largest economies had reached "consensus on principles" during a "serious and constructive" telephone call between their main trade negotiators.

U.S. President Donald Trump said he hoped to sign an agreement with Chinese President Xi Jinping at a U.S. location, perhaps in the farming state of Iowa, which will be a key battleground state in the 2020 presidential election.
