Respected XX of XXGreetings, I am writing this letter to thank you for your kind understanding of our moderate adjustments to our pricing policies. As you may have already known, the cost of the raw materials necessary to our production has moved up greatly in the last few years, and considering the fact that it is to the interests of both of our companies’ that we maintain a cooperation relationship, we have been by far trying to suppress the rise of product prices as best we can. But with the recent increase of labor cost, it has become impossible for us to leave prices the way they were, and thus the new pricing policy. You have shown great understanding when we announced our new price list, and that is certain to help increase our future cooperation, once again you have my thanks on behalf of the whole company. You are very welcome to continue ordering our products, we look forward to in depth cooperation between our two companies.XX of XX。
