Chinese Journal of Mechanical engineering requires authors to declare all competing interests in relation to their work. All submitted manuscripts must include a ‘competing interests’ section at the end of the manuscript listing all competing interests (financial and non-financial). Where authors have no competing interests, the statement should read “The author(s) declare(s) that they have no competing interests”. The Editor may ask for further information relating to competing interests.

Editors and reviewers are also required to declare any competing interests and will be excluded from the peer review process if a competing interest exists.

All manuscripts must be submitted by an author and may not be submitted by a third party.

Any manuscript submitted to CJME must be original and the manuscript must not be under consideration by any other journal. In any case where there is the potential for overlap or duplication we require that authors are transparent. Authors should declare any potentially overlapping publications on submission and, where possible, upload these as additional files with the manuscript. Any overlapping publications should be cited. Any ‘in press’ or unpublished manuscript cited, or relevant to the Editor’s and reviewers' assessment of the manuscript, should be made available if requested by the Editor. CJME reserve the right to judge potentially overlapping or redundant publications on a case-by-case basis.

In general, the manuscript should not already have been formally published in any journal or in any other citable form. If justified and made clear upon submission, there are exceptions to this rule.
