High. Because Alibaba is an international e-commerce platform that attracts buyers and sellers from all over the world, the purchase, quotation, transaction and other links of the international station require participants to be proficient in English for effective communication and exchange. In addition to the English homepage and product descriptions requiring standard English, international buyers will also have high requirements for the seller's English proficiency and communication skills. Therefore, for sellers, English communication skills are also crucial. In addition to language requirements, Alibaba International Station also has a number of audit and certification requirements for sellers, such as business licenses, corporate qualifications, etc., to ensure the transaction security and legality of buyers and sellers on the platform. Therefore, as a seller doing business on Alibaba International Station, you not only need to have English communication skills, but also need to fully understand the platform's relevant rules and requirements to improve the success rate and efficiency of transactions.
