Trump said last Friday the higher charge will take effect on June 4, but Leavitt did not elaborate on the timing.

A U.S. trade court blocked most of President Donald Trump's tariffs in a sweeping ruling on Wednesday that found the president overstepped his authority by imposing across-the-board duties on imports from U.S. trading partners, Reuters reported. The Court of International Trade said the U.S. Constitution gives Congress exclusive authority to regulate commerce with other countries that is not overridden by the president's emergency powers to safeguard the U.S. economy.

After stepping back this month from an escalating and dangerous war of tariffs, the United States and China are now threatening to undermine their uneasy truce, the New York Times reported. On May 12, the countries announced after weekend meetings in Geneva that they would suspend most of their recently imposed tariffs.
