An irrevocable Credit constitutes a definite undertaking of the Issuing Bank, provided that the stipulated documents are presented to the Nominated Bank or to the Issuing Bank and that the terms and conditions of the Credit are complied with.
对不可撤销的信用证而言,在信用证规定的单据全部提交指定银行或开证行,并且这些单据又符合信用证条款的规定时,便构成开证行的确定承诺.
