I am not disputing that the article and others from the US or even the Korean trade department can promise or say what they wish.

A website belonging to America does not replace or superced actual Korean law.

Until the Korean law itself is changed, the trade agreement is just a piece of paper with a promise, it is not actual law.

> No, KORUS [0] is is an actual real treaty, one which the Korean Parliament voted for and ratified. Its provisions have the same effect as regular laws, because the Korean Constitution [1] directly says so:

There are always contradictions between government departments. My country AU for example has different laws which are bested by state laws and those laws are also superceeded by more exact local government laws. The EU is no different, there are treaties with the EU, and many country level laws.

> Treaties duly concluded and promulgated under the Constitution and the generally recognized rules of international law shall have the same effect as the domestic laws of the Republic of Korea.

What exactly is GENERALLY RECOGNISED RULES... ?
