Rebiya Kadeer
On 19 August 2009, PetroChina signed an A$50 billion deal with ExxonMobil to purchase liquefied natural gas from the Gorgon field in Western Australia, considered the largest contract ever signed between China and Australia, which ensures China a steady supply of LNG fuel for 20 years, and also forms as China's largest supply of relatively "clean energy". This deal has been formally secured, despite relations between Australia and China being at their lowest point in years, following the Rio Tinto espionage case and the granting of visas to Rebiya Kadeer to visit Australia.
