Some 20,000 people have protested against Moldova's government, days after the International Monetary Fund said it would not negotiate a new loan agreement with the pro-European leadership.
Two pro-Russian parties organised Sunday's protest, the latest demonstration since September 6 when tens of thousands protested government policies and called for early elections.
Protesters shouted "down with the thieves!" and at least 30 tents were erected in front of Moldova's Parliament in the capital Chisinau.
In a sign of tensions, police guarded the country's main institutes.
An IMF mission began a two-week visit on September 22, a day after Moldova's central bank governor Dorin Dragutanu resigned following protests over $US1.5 billion ($A2.13 billion) that disappeared from three Moldovan banks before parliamentary elections last November.
