The United States has declined to renewrenew/rɪˈnjuː/L2续签；延长（协议、合同等的）有效期to make an agreement, contract, or official document continue for a longer period of time the US-Mexico-Canada Agreement (USMCA) in its current form. A senior US official said the administration 'chose not to rubber stamp a USMCA renewal without addressing existing issues.' If the three countries do not all agree to renew, the deal will have a ten-year countdown to termination. This means the trade pact could expireexpire/ɪkˈspaɪər/L2到期；失效when an official document, agreement, or right stops being valid after a certain period of time as early as 2036.
The USMCA supports about $2 trillion in trade every year. However, the US has unresolved disputes over automotive rules, dairy market access, and stopping China from using the deal. US trade officials want major changes before a long-term extension. Business groups across North America had asked for the pact to be renewed. US steel groups support the decision because annual reviews give negotiators more power to fix parts of the deal.
The trade deal remains in place for now. The lack of a long-term commitment creates uncertaintyuncertainty/ʌnˈsɜːrtənti/L2不确定性；不确定的状态a situation where you are not sure what will happen in the future. As a result, the countries will now meet every year to negotiatenegotiate/nɪˈɡoʊʃieɪt/L2谈判；协商to try to reach an agreement by discussing something in a formal way changes. The ten-year countdown has started. This sets a deadline for reaching a new agreement.
