The Koreans have been trying to sell back M1 Garand’s that were lent to them around the time of the Korean war but the US Government has blocked the importation. For more detailed information check out SayUncle who has blogged about it.
The Korean news website The Chosun llbo has an article about the sale …
A Korean government official said, “It’s difficult to understand why the U.S. opposes the deal now, when we already shipped tens of thousands of these firearms to the U.S. in the early 1990s. We are trying to grasp the real underlying cause of this reversal through diplomatic channels.” He added that because these firearms were originally made in the U.S., selling them back needs approval from Washington.
