Translate the following English sentence to French:
"In spite of this, the Commission was not able to induce Israel to respect these agreements, and only gave vague responses to parliamentary questions, maintaining that it was difficult to obtain reliable proof of the provenance of products, although it has consistently, and quite rightly, made the legal obligations imposed by the agreement clear to Israel."
Malgré cela, la Commission n'est pas parvenue à obliger Israël à respecter ces accords et elle a apporté des réponses vagues aux différentes questions des parlementaires, évoquant sans cesse la difficulté d'obtenir une preuve fiable de l'origine des produits, même si elle a toujours rappelé à Israël les obligations juridiques de l'accord.
