Group 1 - The new demands from the U.S. government may undermine a recently reached trade agreement with the EU, which had previously eased tensions between the allies [1] - The U.S. has proposed a new trade proposal aimed at achieving "reciprocal, fair, and balanced" trade, but EU officials view these demands as excessive [1] - The U.S. is seeking discussions on EU legislation, including digital and technology rules, while the EU insists on maintaining regulatory autonomy [1] Group 2 - In return for concessions, the EU has submitted legislation to lower tariffs on U.S. industrial goods and some non-sensitive agricultural products, pending approval from the European Parliament [2] - Discussions regarding the reduction of U.S. tariffs on steel and aluminum have made little progress, with the EU planning to impose tariffs on foreign steel imports exceeding certain quotas [2] - Concerns have been raised that the U.S. is expanding the list of products subject to the 50% tariff, potentially affecting medical devices and technology, which could weaken the EU's hard-won 15% tariff cap [2]
