House lawmakers and US senators have introduced legislation aimed at tightening restrictions on economic interactions with certain foreign nations. A bill has been offered to end tax breaks for stocks in China, Russia, Belarus, Iran, and North Korea. Concurrently, two U.S. senators have proposed legislation to strengthen the ban on selling crude oil from the Strategic Petroleum Reserve (SPR) to China. This move is part of a broader effort to limit financial and resource-based transactions with countries deemed as foreign adversaries.
