I come from Dandong. Let me give you a brief introduction.
The swindlers in Dandong are all Koreans from Yanbian, Shenyang, who cheat under the guise of trading with North Korea. And they are all on the edge of the law. It is very difficult to give an example. Most of them fail to meet the requirements of crime. Civil cases at most.
There is a common sense: you must know. In most cases, foreign exports are mainly freight forwarders, and there is no need to place orders or sign contracts.
Basic technology:
1, please go to Dandong to discuss trade. You can't come.
2. After you came to Dandong, you were asked to invite Korean businessmen to dinner, give gifts and pay translation fees. It will cost you thousands of dollars. These things are difficult to prove legally.
Let you spend thousands of dollars, I will sign a contract with you and promise to pay you a certain proportion in advance. Let you go back happily, then contact again, and you can't find anyone.
Among the above basic processes, the most conspicuous one is to invite you to Dandong, which is definitely not allowed. If you want to do business, let them pay for it, or just say, find a freight forwarder and we will operate it ourselves and give you a commission.
