Nation is making 'a comprehensive assessment' of Supreme Court ruling

　　China has urged the United States to rescind its unilateral tariff measures imposed on trading partners, and said it would keep a close eye on any "alternative measures" adopted by Washington to sustain hefty duties, the Ministry of Commerce said on Monday.

　　While China remains committed to working with the US for mutual benefit and the stability of the global economy, officials and analysts said that Beijing will take firm countermeasures should Washington take any action that infringes upon its interests.

　　Their comments came after the US Supreme Court scrambled the trade landscape on Friday by striking down sweeping tariffs proposed by US President Donald Trump.

　　However, hours after the ruling, Trump vowed the tariffs would quickly be reimposed in other forms, announcing plans for a new 10 percent "global tariff" under Section 122 of the Trade Act of 1974, which he later raised to 15 percent.

　　Prior to the US Supreme Court's decision, US tariffs on Chinese imports comprised five layers — 2.5 percent most-favored-nation tariffs, 8.4 percent Section 301 tariffs, 11 percent Section 232 tariffs, 10 percent fentanyl tariffs and 5.1 percent "reciprocal" tariffs — totaling 37 percent, according to calculations by Guosheng Securities, a State-owned enterprise headquartered in Nanchang, the capital of Jiangxi province.

　　The Supreme Court ruling invalidates the fentanyl tariffs and the "reciprocal" tariffs on China, cutting the baseline rate to 21.9 percent. But the addition of the new 15 percent "global tariff" again pushes up the composite rate to about 28.6 percent, Guosheng Securities noted.
