<p><strong>R&eacute;sum&eacute; :&nbsp;</strong>Dans notre &eacute;tude nous nous int&eacute;ressons &agrave; la construction d&rsquo;un texte argument&eacute; sous forme de lettre de r&eacute;clamation en fran&ccedil;ais langue &eacute;trang&egrave;re. Cette probl&eacute;matique vient du terrain. En effet, les enseignants de FLE constatent souvent des difficult&eacute;s importantes &agrave; l&rsquo;&eacute;crit chez les publics d&rsquo;apprenants asiatiques. Les apprenants sont &eacute;galement conscients de leurs difficult&eacute;s. Nous proposons donc une analyse de corpus parall&egrave;les en fran&ccedil;ais et en chinois pour ensuite nous pencher sur l&rsquo;&eacute;tude des productions d&rsquo;apprenants sinophones. Nos r&eacute;sultats montrent que les contraintes rh&eacute;toriques diff&egrave;rent fortement entre les deux langues-cultures. L&rsquo;acquisition des principes rh&eacute;toriques est en cours chez les apprenants. L&rsquo;article propose quelques pistes didactiques qui permettent de travailler la comp&eacute;tence r&eacute;dactionnelle avec les apprenants sinophones.</p> <p><strong>Mots-cl&eacute;s : </strong><em>argumentation, expression &eacute;crite, planification, didactique de l&#39;&eacute;crit en L2, rh&eacute;torique contrastive, implication du scripteur, lettre de protestation</em></p> <p><strong>Abstract:&nbsp;</strong>This study focuses on the process of writing an argumentative text in French as a second language by Chinese-speaking learners. The difficulties of Asiatic students in writing process in European languages has been discussed in numerous studies. Teachers and students are aware of these difficulties but they have no clear solutions for remedy these problems. In the first part of the study, we analyse the productions of native speakers of French and Chinese and we show the important rhetoric differences in their productions. The learners&rsquo; writings are also analysed with the same criteria. At the end of the study, we propose some methodological issues for teachers and students.</p> <p><strong>Keywords </strong>: <em>argumentation, writing, planification, didactics of writing in a second language, involvement of the writer, letter of protest</em></p>
