Not really. Britain, and later the US, supported Russia with armaments but as far as Russia supporting Britain, it was a case of "my enemy is your enemy so you are a friend until my enemy is defeated".
I believe the question might be referring to Russia, who "switched sides" midway so to speak.
Russia saw itself as the great protector of all Serbian people, there were even thoughts of a Serbian Empire. Russia was obligated to defend Serbia in a conflict in return for Serbia's agreement of the annexation of Bosnia. More Information: The Ottoman Empire to the south was dwindling. The Russians knew that when states in the Balkans had Nationalist rebellions and seceded from the Ottoman Empire they would be easy to annex into the Russian Empire. Therefore, the Russians supported Balkan Nationalism because they wanted to annex more land and have a better foothold in Europe. The Austrians had a similar idea, figuring they could conquer/annex any land lost to the Ottoman Empire. Therefore, the Austrians annexed Serbia, angered a lot of Serbians and led to the assassination of Franz Ferdinand Hapsburg, a symbolic gesture for the anger the Serbian nation felt toward the Austrians. The Russians felt if they supported Serbia and all those other countries, they would annex them and not face similar problems because they were all Slavs and therefore wouldn't see the Russians so much as foreign rulers. Russia allied with Serbia due to their common Slavic background. Russia was the most powerful Slavic country and felt it was their duty to protect the struggling Serbia. Also, Russia felt it was an obligation to protect their honor. They had just lost a war with Japan, which was a global embarrassment because Japan was not a European power (there was the idea of European supremacy). They had not been able to protect their fellow Slavs before and this was a source of shame, so they felt they had no choice but to ally with Serbia. The Russians and Serbs (Along with every other Slavic country) followed a common belief formally named Pan Slavism. This Pan Slavism entailed that all Slavic countries all shared the same nationality, as well as the fact that they shared a language. Russia was the largest Slavic country, and in that fact, waited an obligation to protect their fellow "countrymen". When Austria-Hungary declared war on Serbia, the Russians were forced to enter the war to protect their cousins.
Germany
Russia was the US's main enemy after WW2

Not too many people consider Russia to be an enemy although many would consider Russia to at least be a competitor. The Chechnya separatists are enemies of Russia.
