According to Article 3(2) of the NPT and NSG the Guidelines, the exporting country should be guaranteed the import country’s willingness to implement nuclear non-proliferation and the level of implementation before the transfer of Trigger List Items. Also, unknown or new end-users could be officially identified through GA procedure. Accordingly, Korea government requests the importing country a formal Governmental Assurance (GA), before issuing an export license. This study summarizes GA items and characteristics. First, GA is The NSG guidelines suggests four items that should be assured by importing countries: peaceful use of export items, full-scope safeguards application, physical protection measures, and retransfer control. Therefore, these four items are generally requested based on the NSG guidelines. However, if they are already guaranteed by bilateral nuclear cooperation agreement, the GA could be based on the nuclear cooperation agreement. The GA procedure could be omitted in the case of concluding an administrative agreement that imposes another implementation procedure. The levels of requested GA requested vary with the countries, since the NSG guidelines are just recommendations that are not legally enforceable. Korea requests the level based on the NSG guidelines. Among the four GA items, peaceful use of export items is the most fundamental obligation, and levels of safeguards and physical protection of the importing country could be verified in advance by reviewing the conclusion status of international agreement with the IAEA. Thus, the important thing for the licensee to consider is to decide the level of retransfer control. The NSG guidelines suggest two levels of retransfer control, taking into account the sensitivity of the export items and the level of safeguards in the end-user country, which is either to receive GA from the third receiving country at an equivalent level with that originally requested from exporting country, or to get a prior consent by the exporting country. The latter should be approached more carefully, as requiring a prior consent is not only to have authority, but also to have responsibility when problem occurs. In addition, the level of retransfer control must be decided through sufficient reviewing on the transaction characteristics, it may affect the domestic export industry.
