The Attorney General considers that there is no controversy with PDVSA
Ecuadornews:

The arbitration notifications filed by the firm Petróleos de Venezuela (Pdvsa) against Ecuador do not represent the existence of a dispute, according to the Attorney General’s Office (PGE).
PDVSA submitted, as published this Journal on September 30, 2018, on May 15, 2018, two communications to notify the controversy in the Refinería del Pacífico projects and in the company Río Napo, in which the Venezuelan firm had participation along with Ecuador.
The foundation to initiate these actions was the Bilateral Investment Treaty (BIT), signed between both countries in 1993 and denounced by the Ecuadorian Government in 2017.
Given this, the Attorney General’s Office replied on June 11, 2018 to the Venezuelan oil company that these communications “did not constitute a notification of the existence of a dispute.” Therefore, according to the entity, the period of direct negotiations provided for in the BIT, which is six months, did not begin to run.
The Attorney General’s Office argued that the communications sent by Pdvsa have a general content and cannot be derived from the controversies that the Venezuelan company supposedly maintains with Ecuador.
Therefore, from the perspective of the Ecuadorian State, “there is no investment controversy with PDVSA.” PDVSA has not yet replied to these offices, said the State Attorney General’s Office, which requested information on this process from Pdvsa Ecuador on September 27. , but until this October 3, 2018 have not responded.
