To this end, contacts and exchanges of views, including on technical matters, shall be facilitated by both Parties.Article 18In order to ensure the correct application of this Protocol, the Community and China offer mutual assistance for the checking of the authenticity and the accuracy of export licences and certificates of origin issued or of any declarations made within the terms of this Protocol.Article 19China shall transmit to the Commission of the European Community the names and addresses of the authorities competent to issue and verify the export licences and the certificates of origin, together with specimens of the stamps used by these authorities and specimen signatures of officials responsible for signing the export licences. China shall also notify the Community of any change in this information.Article 201. Subsequent verification of certificates of origin or export licences shall be carried out at random, or whenever the competent Community authorities have reasonable doubt as to the authenticity of the certificate or licence or as to the accuracy of the information regarding the true origin of the products in question.2. In such cases, the competent authorities in the Community shall return the certificate of origin or the export licence or a copy thereof to the competent Chinese authorities, giving, where appropriate, the reasons of form or substance which justify an enquiry. If the invoice has been submitted, such invoice or a copy thereof shall be attached to the certificate or to the licence or their copies. The authorities shall also forward any information that has been obtained suggesting that the particulars given on the said certificate or licence are inaccurate.3. The results of the subsequent verifications carried out in accordance with paragraphs 1 and 2 shall be communicated to the competent authorities of the Community within three months at the latest. The information communicated shall indicate whether the disputed certificate, licence or declaration, applies to the goods actually exported and whether these goods are eligible for export under the arrangements established by the Agreement. The information shall also include, at the request of the Community, copies of all the documentation necessary to fully determine the facts, and in particular the true origin of the goods.4. For the purpose of subsequent verification of certificates of origin, copies of the certificates as well as any export documents referring to them shall be kept for at least two years by the competent Chinese authorities.5. Recourse to the random verification procedure specified in this Article must not constitute an obstacle to the release for home use of the products in question.Article 211. Where the verification procedure referred to in Article 20 or where information available to the competent authorities of the Community or of China indicates or appears to indicate that the provisions of this Agreement are being circumvented or infringed, the two contracting Parties shall cooperate closely and with the appropriate urgency in order to prevent or remedy any such circumvention or infringement.2. To this end, the competent authorities of China shall, on their own initiative or at the request of the Community, carry out appropriate inquiries, or arrange for such inquiries to be carried out, concerning operations which are, or appear to the Community to be, in circumvention or infringement of the Agreement. China shall communicate the results of these inquiries to the Community, including any other pertinent information enabling the cause of the circumvention or infringement, including the true origin of the goods, to be determined.3. By agreement between the Community and China, officials designated by the Community may be present at the inquiries referred to in paragraph 2.4. In pursuance of the cooperation referred to in paragraph 1, the competent authorities of the Community and China shall exchange any information considered by either contracting Party to be of use in preventing or remedying circumvention or infringement of the provisions of the Agreement. These exchanges may include information on the production of textile products in China and on the trade in the type of products covered by this Agreement between China and third countries, particularly where the Community has reasonable grounds to consider that the products in question may be in transit across the territory of China prior to their importation into the Community. This information may include at the request of the Community copies of all available relevant documentation.5. Where sufficient evidence shows that the provisions of the Agreement have been circumvented or infringed, the competent authorities of China and the Community may agree to take the measures set out in Article 9 (4) of the Agreement, and any other measures as are necessary to prevent a recurrence of such circumvention or infringement.Annex to Protocol A, Article 2 (1)>REFERÊNCIA A UMA IMAGEN>Annex to Protocol A, Article 7 (1): Model
