I refer to the successful cooperation between our two companies in 2006 and 2007 and I believe that you may already be well familiar with our products and their quality. Hence, we are of the opinion that a factory visit may not be necessary prior to the commencement of our cooperation. However, we can assure you that once our cooperation begins, we will be more than happy to show you around our factory. We sincerely hope that you will understand our position.
