Old wounds appear to be opening between Russia and the US over Moscow's decision to grant asylum to Edward Snowden.
Relations between the US and Russia have hit a new low, with Barack Obama, the US president, openly stating that their partnership just is not working.
Washington is still fuming at Moscow's decision to grant temporary asylum to US whistleblower Edward Snowden, and now Obama has pulled out of talks with Vladimir Putin, the Russian president, on the sidelines of the G20 summit.
"I think the latest episode is just one more in a number of emerging differences that we've seen over the last several months - around Syria, around human rights issues - where it is probably appropriate for us to take a pause, reassess where it is that Russia's going, what our core interests are, and calibrate the relationship so that we're doing things that are good for the United States, and hopefully good for Russia as well, but recognising that there are just going to be some differences and we're not going to be able to completely disguise them," Obama declared.
The Russians have called the decision disappointing. But while Snowden may have been the catalyst, Obama and Putin have never been close and differing positions on Syria, missile defence and human rights issues are also a factor in the deteriorating relations.
Russia has been criticised over its treatment of homosexuals after Putin signed a law in June banning what the Russian government calls "gay propaganda".
The law imposes fines on anyone taking part in gay pride demonstrations, or anyone considered to be making homosexuality appear attractive to minors.
The law has triggered outrage across the globe, with some calling for next year's Winter Olympics in the Russian city of Sochi to be cancelled or held elsewhere.
