The US industrial conglomerate previously had given the Alstom board until June 2 to approve the USD 17 billion acquisition deal that has sparked a furor among nationalists and French officials.
"At the request of the French government, we have agreed, in consultation with Alstom, to extend the deadline for consideration by the Alstom board of our proposal until June 23," GE said in a statement.
"We have done so to facilitate ongoing discussions with the government. The industrial project we have presented is good for Alstom, for France and for GE, and our discussions have continued to be constructive. We view this extension positively."
The unit accounts for 70 per cent of Alstom's business, and would leave behind the railway equipment division that manufactures France's prized TGV high-speed trains.
