The Ukrainian delegation, which also includes Fuel and Energy Minister Ivan Plachkov, planned two days of what were expected to be tough negotiations.
Earlier this month, the Turkmen leader said a 25-year contract for natural gas deliveries to Ukraine could only be reached in consultation with Russia, a transit country.
Turkmenistan has also conditioned gas supplies to Ukraine in 2006 on payment of the debt for gas supplies this year.
