In recent years, the proliferation of natural resource trade has caused rising demand in supply of resource products, leading to “widespread anxiety over the security of access to natural re-source.” In context of this, export restrictions have been frequently imposed on resource products, most of which come from the developing world. Recently, known as China − Rare Earths, a case against China’s measures related to the exportation of rare earths was brought to WTO and a panel has been established by request of Japan. It is another sign for the increasingly heated topic of export restrictions during recent decades subsequent to the high profile case China − Raw Materials.Against this backdrop, it is thus vital for exporting countries to seek justifications provided in GATT/WTO when facing challenges to their export restrictions. This thesis aims to elaborate on the issue of applying current possible exception clauses to alleged unlawful export restrictions, in accordance with present articles under GATT 1994 and available case laws. Meanwhile, a highly relevant case China − Rare Earths would be discussed in light of this.
