衛氏朝鮮
It is not clear as to how well defined of an organized state Jin was. It seems likely that it was a federation of small states much like the subsequent Samhan. For the state to be able to contend with Wiman Joseon and send embassies to the court of Han Dynasty China, there was probably some level of stable central authority. Korean historian Ki-baek Lee (1984, p. 24) also suggests that the kingdom's attempt to open direct contacts "suggests a strong desire on the part of Chin [Jin] to enjoy the benefits of Chinese metal culture." However, for the most part Wiman Joseon prevented direct contact between Jin and China.
