Fireworks Vendors on Edge After Trump Threatens to Impose More Tariffs on Chinese Imports Rob Garver WASHINGTON - As President Trump prepares for a key meeting with Chinese President Xi Jinping at the G-20 summit in Osaka later this week, cities and towns across the country are gearing up for annual Independence Day celebrations -- events that could look very different in 2020 if the two leaders are unable to resolve a deepening conflict over trade. The United States has already imposed tariffs on $200 billion in annual imports from China, and is threatening to increase that figure to $500 billion, covering virtually everything shipped from China to the United States. Among the thousands of items that could be affected are the fireworks that Americans are used to seeing burst in the air over their July 4th picnics and barbecues. .
