Britains Vodafone said on Thursday it intended to push ahead with international arbitration in its long-running Indian tax dispute, after the Indian government said it would set up a committee to review retrospective tax claims. Vodafone and India have been locked in a $2.2 billion tax standoff since the British company acquired Hutchison Whampoas Indian mobile assets in 2007. Vodafone thought it had finally secured victory in the case in 2012, when Indias Supreme Court dismissed the tax demand. Indian Prime Minister Narendra Modis new government on Thursday unveiled its first budget and said it would review certain claims.
