答案如下：
Dear Sirs,
We have received your L/C No.4352 for Contract No.96COT491.After checking, we would request you to make the following amendments:
1)The L/C should be confirmed.
2)The L/C should read:’for account of ABC trading Co.,Italy.’
3)’Freight Prepaid’ should be ’Freight Collect.’
4)Inspection Certificate should be issued by the Jiangxi Commodity Inspection Bureau.
5)The credit is to be valid for negotiation in China instead of in Italy.
Please make the above amendments so that we may make arrangements for shipment.
Yours truly
