TIMELINE-Gas crises between Russia and Ukraine

(Reuters) - Ukraine removed conditions on Monday that threatened a gas deal to resume Russian supplies, to resolve a row that has plunged much of Europe into an energy crisis.

Here are some details about recent gas crises between Russia and Ukraine:

* WINTER 2005-2006:

-- Russia and Ukraine clashed over prices for the first time following the 2004 pro-Western "Orange Revolution" which swept President Viktor Yushchenko to power. Yushchenko has tried to withdraw Ukraine from Russia's sphere of influence.

-- A dispute over gas prices -- Ukraine then paid just $50 (33 pounds) per 1,000 cubic metres, Gazprom wanted to charge $230 -- was complicated by accusations of corruption in the energy sector from Prime Minister Yulia Tymoshenko.

-- Gazprom cut off supplies on January 1 2006, but turned them on again a day later. European consumers complained their supplies had been hit. Gazprom accused Ukraine of stealing gas from export pipelines, but Kiev denied this.

-- Ukraine agreed to a price of $95 per tcm and the introduction of intermediary RosUkrEnergo, which soon became a source of conflict over future gas agreements.

* FEBRUARY 2007:

-- Ukraine's parliament passed a law banning the privatisation, sale or lease of gas pipelines, after Russia suggested creating a joint venture to run the system.
