In other news, the United States is reportedly considering delaying the announcement of new tariffs on China until after next week's summit between Chinese President Xi Jinping and US President Donald Trump. This delay could serve to preserve the threat of tariffs as leverage in the upcoming negotiations. The administration had previously intended to release a trade report recommending a 7.5% tariff on Chinese goods before the meeting. The reason for the delay is unclear, but President Trump has frequently used tariff threats to pressure trading partners for concessions.
