Kiev: The Ukrainian government and the European Commission today agreed "immediately" to allow European Union technical observers into Ukraine to monitor gas supplies amid its dispute with Russia, the Ukrainian government said.

The agreement came in telephone talks between Ukrainian Prime Minister Yulia Tymoshenko and European Commission chief Jose Manuel Barroso.

"Yulia Tymoshenko and Jose Manuel Barroso have agreed to immediately send EU technical experts so that they conduct constant monitoring of natural gas supply volumes," the government said in a statement.

Tymoshenko also told Barroso that Ukraine would "ensure ... Uninterrupted transit" of gas once Russia resumes supplies to Europe through Ukrainian territory, the statement said.

Tymoshenko also spoke by phone to German Chancellor Angela Merkel, who said Germany had supported sending the bloc's observers to Ukraine, a separate statement said.

Germany, along with countries such as France, Germany, Italy and Serbia, reported drastic falls in Russian gas supplies.

Meanwhile, Russian Prime Minister Vladimir Putin said Russia would resume gas supplies to Europe via Ukraine when a mechanism is agreed for deploying international observers.

Putin made the comments in a telephone conversation with Czech Prime Minister Mirek Topolanek, whose country currently holds the European Union presidency, his press service said.

"If Ukraine does not allow the transit of Russian gas (to Europe) in the nearest future and Russia is compelled to stop deliveries of gas in transit, then Gazprom will only resume deliveries when a control mechanism is worked out with the participation of international observers," Putin said.
