"The rights to suspend performance and to stop goods in transit in the event of an imminent breach of contract . . . were included in Article 73 ULIS . . . in terms largely similar to those of Article 71 CISG. . . .
"Unlike Article 73 ULIS, Article 71(3) CISG requires notice of the exercise of the right of suspension or stoppage to be given to the other party; this is intended to increase cooperation between the parties. In addition, Article 71(3) . . . provides for the possibility of assurance being provided by a party in order to neutralize an imminent breach of contract. . . ."
