In Thailand, a government spokesman has said that the Prime Minister Abhisit Vejjajiva has cancelled an imminent visit to Russia today. Thailand expelled Viktor Bout, who is suspected of being one of the world's biggest arms traffickers on Tuesday to face trial in the United States after a prolonged legal battle and fierce opposition from his home country Russia. Prime Minister has since cancelled a trip to Saint Petersburg to attend a summit on tigers, but the spokesman said this was to discuss constitutional amendments and denied any link to the extradition.Russian Prime Minister Vladimir Putin is due to host the four-day summit, which begins on Sunday and aims to halt the decline of the big cats.Viktor Bout's sudden extradition came shortly after the Thai cabinet approved his handover in a move that prompted fresh fury from Moscow, which had vowed to do all it could to bring him home. The Russian foreign ministry said his extradition was “illegal” and prompted by US pressure.
