History of Moldavian and Ukrainian relations 
Middle Ages 
Relations between the Moldavian Principality and Zaporizhian Host developed in the context of the political situation in Eastern Europe: Polish-Lithuanian states, the Great Muscovite principality, Ottoman empire, and its vassals - the Crimea Khanate, Walachia and Transylvania. Since Moldavian Prince George Duca (1681–1683) came to control the "Turkish Ukraine", the Zaporozhian - Moldavian relations took one of the most important places in foreign and in domestic policy of Moldavian Principality.
Ukraine, step by step after 2005, conceded several important economic privileges to Moldova. Kiev accepted gas delivery to Moldova for the account of Ukrainian share in the beginning of 2006 and electricity delivery at low tariffs. Ukraine has also accepted the introduction of the monitoring commission of the European Union at the Ukrainian-Moldovan border, as well as implementation of the unified customs procedure for the Transnistrian part of the Moldovan border. Ukraine opened its alcohol market for Moldovan production when Russia imposed a ban on it.
Nevertheless, certain areas remain with unsolved problems. Since 2006 Moldovan authorities have not delivered to Aerosvit the authorisation to operate daily flights to Chişinău. The rail transport remains an important issue, as Ukraine is constructing a new railway line to deviate from the problematic Transnistrian sector, with its frequent blocks of railway transportation. Moldova has not yet transferred to Ukraine the Odessa–Reni highway section, as well as bordering property in the region of Palanca.
The situation remains unresolved with one block of the Kuchurgan power station, as it considered to be on Moldovan territory today for unclear reasons, or at least contested by Ukraine. The construction of the oil terminal in Giurgiulesti is strongly contested by Ukraine for the ecological threat it represents to the Danubian region of Ukraine. Ukraine had transferred 400 meters of Ukrainian bank of Danube to Moldova in 1997, namely in order to make the construction of the terminal possible.
The reciprocal visa free regulation exists for traveling citizens of both in countries respectively. The border between two states may be crossed by presenting a valid passport. If the stay in the country exceeds three days, the person is under obligation to register with the respective country's local police authorities.
