The Russian government wants a dialogue with Germany on the Navalny case.
The Kremlin argues that Russian doctors who treated the opposition leader were much more transparent than the German doctors in Berlin are now.
In the German capital, Navalny was found to have been poisoned with a nerve agent from the novichok group, while the Russians said they had not seen any poison in him.
According to Moscow, no crime has been committed.
A Kremlin spokesman said that Moscow now wants to know from Germany precisely what substance has made Navalny sick. Russian experts are looking into the matter, he said.
Investigators have been ordered to investigate whether anyone attempted to kill Navalny, it was announced earlier today.
The German government and the European Union want a thorough and transparent investigation into what they call a murder attempt.
