Translate the following English sentence to French:
"We think it is splendid that the trade agreement has had built into it a demand to promote democracy in Mexico - including the observance of human rights - but, as long as this demand is not followed up by concrete action, it is merely a case of empty words."
Il faut que l'accord commercial inclue une clause exigeant le développement de la démocratie au Mexique - y compris le respect des droits de l'homme - mais si cette exigence n'est pas suivie d'effets concrets, ce ne seront que de vaines paroles.
