Generally speaking, Amazon contracts need to be in English because Amazon is an international platform that uses English as the primary working language. When signing a contract, make sure you understand the terms and conditions in the contract, especially those related to Amazon's policies and regulations. If you need to translate the contract, make sure you can find a reliable translation service to help you understand the contract. Also, please note that different regions may have different legal provisions and contract requirements. Therefore, it is best to consult a local legal professional or lawyer to learn more about the requirements and considerations of the contract.
