Mr. President,
:
Please accepot our apologies for what to A and B. For both the end of an appointment and B, they are moved, unfortunately. I understand this announcement could make our earnest conversation. For shipping, there are rooms full of XXX YYY incomplete due to late arrival of spare parts for shipment subcontracting factories.For B, there are parts of Article XXX ZZZ incomplete batch B. We expect completion of these two points on Friday.
We understand that this delay may cause pain.
