The US has intensified global trade tensions by doubling import tariffs on steel and aluminum to 50%, following a new executive order signed by President Donald Trump on June 3. The move, aimed at strengthening American manufacturing, is expected to have far-reaching consequences across global supply chains. 

Industry observers warn that this tariff hike may further strain US trade relations, disrupt global steel flows, and add downward pressure on Asian steel prices due to reduced export access. Additionally, the increased trade barriers are seen as contributing to global economic uncertainty, with concerns over weakening demand and escalating protectionism. 

The policy highlights the growing shift toward inward-looking trade strategies, with potential ripple effects on industrial production and international cooperation.
