Edward Natapei of the VP became Prime Minister in 2001 and went on to win the 2002 Vanuatuan general election. The 2004 Vanuatuan general election saw Vohor and the UMP return to power, however Vohor lost much support over a secret deal to recognise Taiwan in the China-Taiwan dispute and was unseated in a confidence vote less than five months after taking office, being replaced by Ham Lini. Lini switched back recognition to the People's Republic of China and the PRC remains a major aid donor to the Vanuatu government. In 2007 violent clashes broke out in Port Vila between migrants from Tanna and Ambrym, in which two people died. Lini lost the 2008 Vanuatuan general election, with Natapei returning to power, however Vanuatu politics then entered a period of turmoil. There were frequent attempts by the opposition to unseat Natapei via the use of no confidence votes – though unsuccessful, he was briefly removed on a procedural technicality in November 2009, an action that was then overturned by the Chief Justice. Sato Kilman of the People's Progressive Party (PPP) managed to oust Natapei in another confidence vote in December 2010, only to be removed in the same manner himself by Vohor's UMP in April 2011, however the latter was deemed invalid on a technical point and Kilman returned as PM. However the Chief Justice then overturned Kilman's victory, with Natapei returning to power for 10 days, at which point the Parliament voted in Kilman once more. Kilman managed to remain in office for two years, before being ousted in March 2013.
