The Minister for Foreign Affairs, Charlie Flanagan, is set to meet with his Egyptian counterpart today to discuss the case of Ibrahim Halawa.
It comes as concerns are being raised about the condition of the Irish teenager in jail in Egypt.
Ibrahim will have to wait until June 6 before his case comes before the courts in Cairo after it was postponed again yesterday.
The Minister for Foreign Affairs is set to meet with his Egyptian counterpart today at a gathering in New York, where he is expected to express his disappointment over the teenager's case.
Amnesty Ireland Chief Colm O'Gorman says they are becoming more and more concerned about Ibrahim.
Mr O'Gorman said: "We know that he is innocent of many of the charges that are being made against him, there is no question that he is involved in any violence, there is no suggestion or evidence to link him to any violent crime.
"He is a prisoner of conscience detained for peacefully exercising his right to freedom of expression.
"He was 17 when he was arrested, he was shot in the hand, received no proper medical treatment for that. We are very concerned about conditions in Egyptian prisons generally and particularly for someone of Ibrahim's age."
