The United States has officially decided not to renew the United States-Mexico-Canada Agreement (USMCA) in its current form. Instead of a long-term extension, the agreement will now undergo annual reviews.

美國已正式決定不以目前形式續約《美墨加協定》（USMCA）。該協定將不再進行長期延長，而將改為每年進行審查。

The Trump administration decided against a 16-year extension that would have kept the pact active until 2042. Consequently, the agreement will now be reviewed every year until it expires in 2036, unless one of the countries decides to leave. The administration emphasized that the current framework is not effective enough in reducing U.S. trade deficits or fixing existing problems.

川普政府決定不採取 16 年的延長方案，否則該協定將維持有效至 2042 年。因此，該協定現在將每年進行一次審查，直到 2036 年到期為止，除非其中一個國家決定退出。政府強調，目前的框架在減少美國貿易逆差或解決現有問題方面不夠有效。

In the automotive industry, a major disagreement involves the 'rules of origin.' The U.S. government wants to increase the regional value requirement for vehicles from 75% to 82%, and it insists that 50% of that value must be produced within the U.S. Analysts assert that these changes could lead to higher operational costs and require expensive new investments. Furthermore, the administration intends to use these talks to reduce the North American supply chain's dependence on China.

在汽車工業方面，一個主要的爭議點在於「原產地規則」。美國政府希望將車輛的區域價值含量要求從 75% 提高到 82%，並堅持其中 50% 的價值必須在美國境內生產。分析師主張，這些變更可能會導致營運成本增加，並需要昂貴的新投資。此外，政府打算利用這些談判來減少北美供應鏈對中國的依賴。

Different groups have different views on this situation. For example, the U.S. Chamber of Commerce and car industry groups argue that stability is necessary to protect investments. On the other hand, domestic steel producers welcome the annual reviews because they provide more bargaining power. Meanwhile, Canadian officials prefer a long-term renewal to ensure certainty, although they believe these disputes can be solved.

不同團體對此情況持有不同看法。例如，美國商會和汽車工業團體認為，穩定性是保護投資的必要條件。另一方面，國內鋼鐵生產商則歡迎年度審查，因為這提供了更多議價能力。同時，加拿大官員更傾向於長期續約以確保確定性，儘管他們認為這些爭端是可以解決的。

Although the USMCA is still active, the lack of a long-term extension creates economic uncertainty as the three countries begin a cycle of yearly negotiations.

雖然 USMCA 仍然有效，但缺乏長期延長將在三國開始年度協商週期之際，造成經濟不確定性。
