No contract has been signed since the beginning of our cooperation, so we need to supplement a contract for better cooperation in the future. We put forward some clauses and fixed rate changes in the contract, and hope that we can discuss the best result and confirm the final contract sample. We propose the change of fixed rate mainly from the change of storage. The reason for our change is the substantial increase of land lease cost and fuel. We hope to get your understanding and support, and look forward to your feedback.
