According to Securities Times, on April 2, 2025, the US government announced the imposition of "reciprocal tariffs" on Chinese goods exported to the US. The US approach violates international trade rules, severely undermines China's legitimate rights and interests, and is a typical unilateral bullying practice. In accordance with the Tariff Law of the People's Republic of China, the Customs Law of the People's Republic of China, the Foreign Trade Law of the People's Republic of China, and other relevant laws and regulations, as well as the basic principles of international law, and with the approval of the State Council, the Customs Tariff Commission of the State Council will impose additional tariffs on imported goods originating from the US starting from 12:01 on April 10, 2025. The relevant matters are as follows: 1. An additional 34% tariff will be imposed on all imported goods originating from the US, based on the current applicable tariff rates. 2. The current bonded and duty-free policies remain unchanged, and the additional tariffs imposed this time will not be exempted. 3. For goods that have already departed from the place of shipment before 12:01 on April 10, 2025, and are imported between 12:01 on April 10, 2025, and 24:00 on May 13, 2025, the additional tariffs specified in this announcement will not be imposed.

According to CCTV News, on April 4 local time, Fed Chairman Powell stated that the US Fed was shocked by the scope of tariffs imposed by US President Trump, indicating that the economic impact of the tariffs will be greater than previously thought.

Powell said that the extent of the tariff hikes will clearly far exceed expectations, and the economic impact may be the same, including rising inflation and slowing economic growth. The scale and duration of these effects remain uncertain. It is reported that Powell previously stated that the inflationary effects of tariffs are likely to be "temporary."

Powell declined to reveal whether he believes the US economy is heading toward a recession, but he acknowledged that the uncertainty of trade policy has put pressure on businesses, and an increasing number of forecasts indicate that the risk of a recession is rising.
