From the FIJ:

The Juventutem International Federation expresses all its gratitude to the Common Father Pope Benedict XVI for the publication of the Motu Proprio Summorum Pontificum. In the cover letter to the bishops we read with emotion the following quote where the impact of the Gregorian Mass on "young persons" is described as the element having played a decisive part in improving the answer to the need for a clearer juridical regulation on the traditional Roman liturgy. Juventutem gives thanks to God for having been able to bear witness to the permanent value and power of sanctification of the Gregorian liturgy among today's youths:

"Immediately after the Second Vatican Council it was presumed that requests for the use of the 1962 Missal would be limited to the older generation which had grown up with it, but in the meantime it has clearly been demonstrated that young persons too have discovered this liturgical form, felt its attraction and found in it a form of encounter with the Mystery of the Most Holy Eucharist, particularly suited to them. Thus the need has arisen for a clearer juridical regulation which had not been foreseen at the time of the 1988 Motu Proprio."

We haven't forgotten that already in 2005 Pope Benedict XVI prayed for Juventutem:

"From protocol N. 11.234, from the Secretary of State dated July 22, 2005, addressed to Juventutem General Delegate:"The Holy Father has been informed that the Juventutem delegation will attend World Youth Day 2005 in Cologne. Please be assured that His Holiness is praying for all the groups who will gather for this significant occasion. With every good wish (...)".

Juventutem feels all the more encouraged to continue helping with the sanctification of youth worldwide through the Roman traditions of the Catholic Church.
