One day after sparring with Russia over missile defence and Kosovo, US Secretary of State Condoleezza Rice launched a new attack against its cold war foe today for a slide in democracy.
Underlining the difficult relationship Washington has with Russia, the top US diplomat described it as a mix of "cooperation and competition, friendship and friction" and said Moscow needed to improve its record on democracy. "Democratic institutions and an open society are not a source of weakness.
Nor is freedom of speech and freedom of the press just a nuisance," Ms Rice said in a speech where she received an award for her contribution to German unification while she was a Soviet specialist working at the White House. She said Russia needed to have strong, independent institutions as well as a strong judiciary and legislature.
"(There needs to be) a strong, independent society with a strong, independent media and free and fair elections with access for monitors," Ms Rice added.
The United States has been particularly critical of Russia's crackdown on the media and a general erosion of freedoms as the Kremlin centralised its power.
Another irritant in the relationship has been the US proposed missile shield as well as Moscow's suspension of its involvement in the Conventional Forces in Europe treaty.
"We find Russia's recent missile diplomacy difficult to understand and we regret Russia's reluctance to accept the partnership in missile defense that we have offered," Rice said in her speech. The United States wants to deploy a radar system in the Czech Republic and 10 interceptor missiles in Poland by 2011-12.
It says the system would counter threats from so-called "rogue states" like Iran and North Korea, but Moscow sees it as an encroachment on its former sphere of influence.
