• China conducts a "full assessment" of the US Supreme Court's tariff ruling.
• President Trump has announced a new 15% tariff on imports following the ruling.
• China insists that unilateral tariffs violate international rules and harm global trade.
• The new tariffs are set to last for 150 days with some product exemptions.
• Trump's planned visit to China is expected to feature discussions on trade issues.

Following the U.S. Supreme Court's ruling that invalidated several tariffs imposed by President Donald Trump, China has called on the U.S. to cancel what it describes as "unilateral tariff measures." The court's decision determined that Trump does not have the legal authority under a 1977 law to enforce such tariffs, prompting China's commerce ministry to conduct a "comprehensive assessment" of the ruling's impact, stating, "there are no winners in a trade war and that protectionism leads nowhere," according to Reuters and Channel News Asia.

In reaction to the court's ruling, Trump swiftly announced an increase in tariffs on imports to 15% from 10%, based on a different legal provision, Section 122. These new tariffs are set to take effect shortly and are intended to be temporary, lasting for 150 days, with some exemptions for certain products. Amidst these developments, China's ministry emphasized that "U.S. unilateral tariffs ... violate international trade rules," further urging the U.S. to reconsider its economic strategies, according to Reuters and India Times.

China's foreign ministry reiterated its commitment to closely monitoring U.S. actions, particularly as Washington considers alternative measures to maintain elevated tariffs, such as ongoing trade investigations. It insisted that such confrontation is "harmful" to both nations and the global economy. The upcoming meeting between Trump and Xi Jinping in April is expected to address these pressing trade tensions, although U.S. Trade Representative Jamieson Greer has indicated that the intention is not to escalate disputes during this engagement, according to India Times and Channel News Asia.

The current tariffs and ongoing trade negotiations come at a time when several countries, including Switzerland, are preparing for the implications of prolonged U.S. tariffs. Swiss officials have expressed that there appears to be no end in sight for these obligations, illustrating the broader uncertainty in international trade relations. Responses from European officials have also echoed similar concerns, noting that the U.S. must adhere to the agreements set out in past trade deals amid these changing policies, according to Reuters and India Times.
