Subsequently, a disputeconcerning the settlement of the additional costs arose, and an arbitration is being conducted inSingapore. During the course of the arbitration, the Plaintiff demanded that the JV returns the fullamount of the funds by the end of December 2020, but the JV refused on the grounds that the correct
