pdq, American companies are pumping oil in locations- 'foreign lands'- around the globe. The practice, however, is to use citizens of the country involved as employees and managers wherever possible.

Most of the oil in Canada is 'pumped' (Hibernia, e. g.) or mined (tar sands) by American companies and partners, but the employees and management are Canadian; e. g., affiliates such as Imperial Oil Ltd, or Syncrude (with partners) where Exxon Mobil is the owner of Imperial. Other companies such as Royal Dutch Shell have set up similar affiliates in Canada, staffed by Canadians. BP Canada Energy Co., ConocoPhillips Canada, Chevron Canada Resources, etc.

China has not bid or applied for Canadian tracts, although their two major companies have expressed interest. The Canadian government would set the rules of operation. Chinese operators, if they stayed in Canada, would come in as landed immigrants.

BP and Royal Dutch Shell have U. S. organizations for the U. S.; policy at the highest level may be set in London or the Hague, but employees and management in the U. S. is nearly all American, not UK or Dutch.

Major integrated petroleum companies, regardless of where ownership resides, use local employees wherever possible, and mostly have set up affiliate companies for management and direction, under the laws of the countries involved.
Such is necessary when operations must be global.
