Petrokaz takeover may face Kazakhstan opposition

Chinese state oil firm CNPC may face Kazakh government opposition to its planned $4.2 billion takeover of Canada’s PetroKazakhstan, possibly over ownership of the Central Asian nation’s largest refinery, industry sources said.

The Kazakh government has declined to comment on the sale of PetroKaz, whose operations are based in the Central Asian state, and sources said the government had not yet given its blessing to the deal.
