The proposal is contained in a report on the EU's strategic energy review, which is set be voted upon tomorrow in the European Parliament.
French MEP Anne Laperrouze (ALDE), author of the report and vice-chair of the Parliament's committee on industry, research and energy, strongly supports Nabucco and regrets the modest progress made towards its implementation so far.
But she also stresses the need to diversify potential suppliers as uncertainties mount about the ability of Caspian countries to quickly fuel Nabucco with the necessary gas.
In an explanatory statement, Laperrouze says she "advocates an approach geared to conciliation in the dialogue with Russia, which supplies 42% of the EU's gas, as well as 100% of the gas imported by Poland, Finland and the Baltic states".
According to Laperrouze, the solution to the problem may lie in Moscow. In her report, she suggests that instead of competing with Russia, the EU would have more chance of completing the Nabucco project with the help of Moscow.
"[The European Parliament] hopes, by way of example, that the Nabucco gas pipeline project will be carried out in cooperation with Russia in order to avoid competition between two gas pipelines and to be able ultimately to transmit gas from Russia, Iran or the Caspian Sea," the report says.
The MEP believes relations between the EU and Russia to be "based on interdependence" and that, in continuing negotiations, "the EU should refrain from demanding ratification of the Energy Charter, while reminding the Russian authorities of their endorsement of the principles of the Energy Charter, the principles covered by agreements such as accession to the WTO, and the particular problem of uranium enrichment, which requires specific negotiation between the EU, the United States and Russia".
