求教 这封邮件怎么回？

在5个月前寄过一次样品给他，后来就没了音讯，前几天我又写了一封邮件给他，他及时给我回复了，现在我该怎么回这个邮件？ dear c, thank you for your email and follow up. samples received and evaluated and we look forward for a future business, but unfortunately the business was very low all the year till date due to the politic situation and the war effects in syria. on first opportunity we will be in contact with you. br jeff
