1. T/T: T/T is one of the most commonly used payment methods in international trade. The buyer will remit the payment to the bank account designated by the seller through the bank. This method is fast and safe, but it may require some bank charges.

2. Letter of credit: A letter of credit is a bank guarantee issued by the buyer's bank. The seller can get payment from the issuing bank after delivering the goods according to the conditions stipulated in the letter of credit. Letters of credit provide some protection for buyers and sellers, but the procedures are complicated and the expenses are high.

3. Alipay and WeChat payment: These two digital payment methods are very popular in China and can be used to collect money in international trade. Buyers can transfer money to sellers through Alipay or WeChat payment.

4.PayPal: PayPal is an online payment platform, which is widely used in small transactions in international trade. The buyer can pay the seller by credit card or bound bank account.

5. Cash and draft: In some cases, payment in international trade can be made in the form of cash or draft. This usually requires a foundation of trust and mutual understanding, which is not common.

Please note that the actual payment method may be different due to differences in negotiation, trade nature, national regulations and company policies. In international trade, it is recommended to negotiate with buyers and sellers to choose a payment method suitable for both parties and ensure compliance with relevant trade laws and regulations.
