The United States is seeking to block a deal between OPEC and non-OPEC nations to stabilize oil markets, Venezuelan President Nicolas Maduro said on Tuesday. 
Maduro  accused  Washington of applying “war-like” pressure to prevent an agreement. 
“You can’t imagine all the pressure that is coming from Washington to ensure the failure of the efforts we have made during the last year to create a common strategy among OPEC and non-OPEC producers to stabilize the market and prices,” Maduro said during his weekly televised broadcast.
Ahead if the meeting, Oil prices rose to a four month high over worries that the result of next Sunday’s meeting of producers in Qatar aimed at freezing current output levels would fail to improve the current supply-demand balance. 
the US benchmark West Texas Intermediate crude delivery climbed 64 cents to $40.36 a barrel on the New York Mercantile Exchange.
In London, Brent North Sea oil for June delivery rose 89 cent to $42.83 a barrel.
