As one of the members of a seven-man delegation created by Catholicos Jacob IV and the support of Georgian King George XI he visited Constantinople in 1678.

When the Catholicos died, the plan was abandoned, but Ori independently resolved to complete the mission and journeyed to Venice, Paris and Vienna.

He joined the French army of Louis XIV, and entered into contact with the high political circles of France, in course of which he constantly raised the question about the liberation of Armenian people from the foreign yoke; however, he was met with cold indifference.

Hoping that the question of Armenia would become the object of consideration in the highest diplomatic circles of European states, German prince sent Ori with a letter of recommendation to the emperor of Austria and the ruler of Florence.

It was agreed that a special envoy should be sent to Persia headed by Ori, to study the situation, the will of the locals, gather information on the fortresses and roads of the country and so forth.

In order not to excite suspicions, Ori would say that he was sent by the Pope of Rome, to the court of Shah Husayn for the purpose of gathering information on the well-being of the Christians in Persia.
