 Venezuela responded to the declaration with a decree issued on 27 May 2015, including the maritime area in dispute in its national marine protection sphere, thus extending the area that the Venezuelan Navy controls into the disputed area.This in turn caused the government of Guyana to summon the Venezuelan ambassador for further explanation.The tensions have further intensified since and Guyana withdrew the operating license of Conviasa, the Venezuelan national airline, stranding a plane and passengers in Georgetown.
