2。 Of course. Either party has the right to terminate the performance of the contract if it encounters problems during the performance of the contract. But it must be treated as a breach of contract.
3。 Meet. Because the contract has a clear (no obvious unreasonable) breach of contract, and the material requirements are the subject matter, beyond reproach.
4。 If the amount of breach of contract is too high, it should be negotiated when signing the contract, and it should not be reconsidered after the accident. What is too high? There is no legal basis.
5。 The key point of this case is that Party B did not actively communicate with Party A to change the performance of the contract and the corresponding terms, but changed the delivery date and the subject matter of the contract privately knowing that the contract could not be fulfilled (even if the national policy changed). Therefore, bear all the liability for breach of contract. The specific handling method is to conduct mediation and negotiation on the amount of breach of contract first. If negotiation fails, Party B will get full payment and terminate the contract.
