Can the invocation of a bank guarantee be prevented by initiating arbitration proceedings?

If the bank guarantee is unconditional, arbitration proceedings would in no way affect the enforcement of the guarantee. This is because an unconditional bank guarantee is independent of the main contract which refers disputes to arbitration.However, if the bank guarantee includes a clause to the effect that it could not be invoked prior to the decision of the arbitrators, such a bank guarantee, which is conditional, cannot be invoked and an injunction can be granted.
