MILAN, Sept 5 (Reuters) - German gas importer Uniper does not rule out Europe's biggest economy will eventually consider gas rationing following Russia's decision to indefinitely halt gas flows via the Nord Stream 1 pipeline.

"We cannot rule out that Germany might look at rationing gas as something that might have to be considered," CEO Klaus-Dieter Maubach told Reuters in an interview on the sidelines of the Gastech conference in Milan.
