Closer to home, you might be interested in looking up on the proceedings of the "Oriental Orthodox-Roman Catholic Consultation" here in North America, which has been meeting yearly since its establishment in 1978.
The Oriental Orthodox Chairman is the Rev. Chor-Episcopos John Meno. The Oriental Orthodox side is sponsored by the Standing Committee of Oriental Orthodox Churches of America, and includes representatives from the Armenian, Coptic, Ethiopian, and Syrian Orthodox Churches.
The Roman Catholic Chairman is Bishop Howard Hubbard of Albany, NY, supported by the Secretariat for Ecumenical and Interreligious Affairs of the USCCB headed by the Rev. Ronald G. Roberson, CSP, of CNEWA fame.
The joint consultation has issued the following official reports:
1) "Purpose, Scope and Method of the Dialogue between the Oriental Orthodox and Roman Catholic Churches" (November 1980).
(2) "Agreed Statement on the Eucharist" (June 9, 1983).
(3) Oriental Orthodox-Roman Catholic Interchurch Marriages and Other Pastoral Relationships was published with the authorization of the Consultation in 1995. It contains useful studies, guidelines, and documentation pertaining to our relationship. (Washington, DC: United States Catholic Conference Publications, 1995). [Publication No. 097-4]
(4) "Guidelines Concerning the Pastoral Care of Oriental Orthodox Students in Catholic Schools" (June 7, 1999)

Of course, the International Commission slated to meet in Egypt later this month carries "more weight."
But the "locals" have been at it for almost 25 years!
