海运保函在现代海上货物贸易中已成为一项实践规则,然而凭保函换取清洁提单,依保函无单放货,在便利贸易的同时也有可能使得买卖双方及承运人等权利人遭受利益上的损害。因而本文认为有效针对海运保函的弊端进行风险防范,对国际贸易的安全有极大的促进意义。 Maritime bond has become a practice rule in the modern maritime trade. However, in exchange for a clean bill of lading with a letter of guarantee, it is also possible for the right to damage such as the buyer and the seller and the carrier to suffer damages while facilitating trade . Therefore, this paper believes that the effective prevention of the disadvantages of the maritime bond is very significant for the security of international trade.
