 Moldova has also achieved a Free Visa Regime with the EU which represents the biggest achievement of Moldovan diplomacy since independence.Still, growth has been hampered by high prices for Russian natural gas, a Russian import ban on Moldovan wine, increased foreign scrutiny of Moldovan agricultural products, and by Moldova's large external debt.Over the longer term, Moldova's economy remains vulnerable to political uncertainty, weak administrative capacity, vested bureaucratic interests, corruption, higher fuel prices, Russian pressure, and the separatist regime in Moldova's Transnistria region.
