US Undersecretary of State for Political Affairs, Thomas Shannon, signed documents that allowed a Canadian company TransCanada to begin construction of the Keystone XL Pipeline on the border of USA and Canada in Montana.
This statement was made by the press office of the State Department. According to it, the US government gave TransCanada a permit for the construction, connection, management and maintenance of the pipeline on the US-Canadian border in Phillips County, in Montana, for the purpose to import crude oil.
Now the company must obtain similar permit to extend a string of the pipeline to the territory of Nebraska.
The President of the United States, Donald Trump, is expected to make a statement soon on this matter.
