On 29 September 2016, the Court of the Appeal of the Republic of Singapore issued the judgment concerning Sanum Investment Limited v. The Government of the Lao People’s Democratic Republic. In this judgment, the Court declared that the PRC-Laos BIT was applicable to Macau SAR. However, the judgment made by the Court is wrong and thus triggered a series of ridiculous conclusions because of the wrongful interpretation on Article 31 of the 1969 Vienna Convention on the Law of Treaties, the wrongful identification on the nature of the customs international rule for the “moving treaty frontier” rule, and the inappropriate standard of proof on the issue of “otherwise established”.
