Since the age of Lord Mansfield, who laid the foundation of the modern English insurance contract law in the second part of the 18th century, English insurance law has developed a unique rule of warranty. Lord Mansfield adopted very different approach and afforded such a strict legal character to insurance warranty, because the promise, given by the insured, played an important role for the insurer to assess the scope of the risk insured at that time. It is still important that the insured keep his promises strictly to the insurer under the insurance contract, but legal environments have changed dramatically since the times of Lord Mansfield. English Law Commission proposed some proposals for reforming the warranty regime to reflect the changes of legal environment in CP 2007. This article is, therefore, designed to examine the proposals and consider their legal and practical implications. The proposals of Law Commission is summarized as following. First, in CP 2007, Law Commission made two principal proposals for reform of the law on warranty. The first is that the insurer should not be entitled to rely on a breach of warranty unless the insured has been provided with a witten statement of what they have undertaken under warranty. The second is that the insurer should not be entitled to reject a claim on the ground that the insured has breached a warranty unless there was a causal connection between the breach and the loss. Secondly, for consumer insurance, the rule requiring a causal connection would be mandatory, whereas for business insurance, it would be possible for the parties to agree on the effect a breach of warranty should have, provided they use clear language to express their intentions. Thirdly, where the insured contracted on the insurer's written standard terms of business, some statutory controls would be afforded to the contract to ensure that the cover was not substantially different from what the insured reasonably expected. Finally, Law Commission propose that a breach of warranty give the insurer the right to terminate the contract, rather than automatically discharging it from liability, but (unless otherwise agreed) only if the breach has sufficiently serious consequences to justify termination under the general law of contract. Having evaluated the proposals of the Law Commission and considered their legal and practical implications, it is quite clear that the proposed rule interfere with freedom of contract and create legal uncertainty. But change can not made without any victims, so Law Commission's attempt to change severe and injust aspects of the warranty regime would be very welcomed and respected.

According to the CISG, there are no special regulations for a reasonable period of time among the obligations to notify the contractual suitability of the goods. As a result, many disputes arise in 'notification within a reasonable period' despite being the most important treaty in practice in defining the obligation to notify nonconformities according to the suitability of goods for each case. Regarding the interpretation of Article 39 of the CISG, various judgments and arbitration decisions are being made in each country for a reasonable period to notify that the goods are not suitable for the contract.There are criticisms that these various views are too harsh on the buyer in the buyer's obligation to notify.It is important to create a unified principle because courts or arbitration agencies of the Contracting States of this Convention interpret in various ways the reasonable period of violation of the contract of goods stipulated in the Convention. Since most of the international commodity trading transactions around the world are regulated by the CISG, it is necessary to analyze and interpret cases in which this Convention is applied in court or arbitral tribunal of each country to derive a unified principle.

CISG articles 34 and 37 clearly allow the seller to cure any nonconformity in documents of sale or performance prior to the date for delivery if it does not cause the buyer unreasonable inconvenience or unreasonable expense. CISG article 48 allows a seller to cure the performance even after the date for delivery if it does not cause the buyer unreasonable delay, unreasonable inconvenience or unreasonable uncertainty of reimbursement by the seller of expenses advanced by the buyer. The wording any failure to perform is broad enough to include a delay. The seller's right to cure relates to all his obligations. The seller may remedy 'any failure to perform his obligations'. This language is broad enough to include a defect in documents. In some cases the fact that the seller is able and willing to remedy the non-conformity of the goods without inconvenience to the buyer, may mean that there would be no fundamental breach unless the seller failed to remedy the non-conformity within an appropriate time. It cannot generally be said what unreasonable inconvenience means. This can only be decided on a case-by-case basis. The seller must bear the costs involved in remedying a failure to perform. The curing of a failure to perform may have influence on the amount of the damage claimed. Insofar as the seller has the right to cure, the buyer is in that case obliged to accept the cure. If he refuses to do so, he can neither avoid the contract nor declare a reduction in price. This rule clearly shows the underlying concept of the CISG, to keep to the contract, if possible. Should the buyer requires delivery of substitute goods and the seller offers repair, it depends on the expense each case. The buyer must receive the request or notice by the seller. The relationship between the seller's right to cure and the buyer's right to avoid the contract is unclear. The buyer's right to avoid the contract should not nullify the seller's right to cure if the offer is reasonable. In addition, whether a breach is fundamental should be decided in the right of the seller's offer to cure.

CISG article 74 establishes the general formula applicable in all cases where an aggrieved party is entitled to recover damages. It provides that damages for breach of contract comprise all losses, including loss of profits, caused by the breach, to the extent that these losses were foreseeable by the breaching party at the time the contract was concluded. An aggrieved party may claim under article 74 even if entitled to claim under article 75 or 76. The latter articles explicitly provide that an aggrieved party may recover additional damages under article 74. Articles 75 and 76 apply only in cases where the contract has been avoided. Article 75 measures damages concretely by reference to the price in a substitute transactions, while article 76 measures damages abstractly by reference to the current market price. Article 76 (1) provides that an aggrieved party may not calculate damages under article 76 if it has concluded a substitute transaction under article 75. If however, an aggrieved party concludes a substitute transaction for less than the contract quantity, both articles 75 and 76 may apply. Pursuant to article 77, damages recoverable under articles 74, 75 or 76 are reduced if it is established that the aggrieved party failed to mitigate losses. The reduction is the amount by which the loss should have been mitigated. Article 78 entitles a party to interest on the price and any other sum that is in arrears.

The purpose of this study is to find out some countermeasure to Korean companies entered Chinese market through analyzing an arbitration case resolved by CIETAC applied of Chinese Commission Agency Law and CISG. China create legal relationship between the principal and the third party under Chinese Consignment Contract Law. Korean companies so make sure whether this Contract is included when they conclude international commercial contract. If yes, they have to prove their recognition for the relationship between the principal and the commission agent when needed. If the parties agreed an additional period of time of delivery and the seller do not deliver the goods within this period, this breach might be regarded as fundamental nature and the buyer could declare the contract avoided. In addition, late delivery might also be regarded as fundamental breach when market price is fluctuated. It is understandable that attorney's fees is recoverable one, but it is not understandable that arbitrator's extra expenses such as travel and accommodation expenses is not recoverable with the reason that arbitrator comes outside of the country.
