Numerous countries around the world are facing the prospect of new tariffs on their exports to the United States on Aug. 7, a potential blow to the global economy, because they haven't yet reached a trade deal with the Trump administration.

South Africa faces a 30% tariff on its exports to the United States starting next week, a move expected to cost tens of thousands of jobs after the country failed to secure a trade deal before a deadline set by U.

Cambodia will scrap tariffs on US goods and pledged to buy as many as 20 Boeing Co. 737 Max jets in a bid to narrow its trade gap with Washington, according to Deputy Prime Minister Sun Chanthol.
