The Holy Father has expressed His desire that this Day of Prayer occur annually on May 24 - as the Marian Shrine of Sheshan in Shanghai is venerated on this day (Feast of Our Lady Help of Christians) every year.

In a Letter that His Holiness wrote to the Catholics of China in May 2007, He assured the Catholics of the People’s Republic of China that the world would be united in prayer for them on this day.

The Holy Father has composed a prayer to Our Lady of Sheshan especially for this international day of prayer, and His Holiness has requested that this prayer be recited every year on May 24.  

Prayer to Our Lady of Sheshan

Virgin Most Holy, Mother of the Incarnate Word and our Mother,
venerated in the Shrine of Sheshan under the title "Help of Christians",
the entire Church in China looks to you with devout affection.
We come before you today to implore your protection.
Look upon the People of God and, with a mother's care, guide them
along the paths of truth and love, so that they may always be
a leaven of harmonious coexistence among all citizens.
 
When you obediently said "yes" in the house of Nazareth,
you allowed God's eternal Son to take flesh in your virginal womb
and thus to begin in history the work of our redemption.
You willingly and generously cooperated in that work,
allowing the sword of pain to pierce your soul,
until the supreme hour of the Cross, when you kept watch on Calvary,
standing beside your Son, who died that we might live.
 
From that moment, you became, in a new way,
the Mother of all those who receive your Son Jesus in faith
and choose to follow in his footsteps by taking up his Cross.
Mother of hope, in the darkness of Holy Saturday you journeyed
with unfailing trust towards the dawn of Easter.
Grant that your children may discern at all times,
even those that are darkest, the signs of God's loving presence.
 
Our Lady of Sheshan, sustain all those in China,
who, amid their daily trials, continue to believe, to hope, to love.
May they never be afraid to speak of Jesus to the world,
and of the world to Jesus.
In the statue overlooking the Shrine you lift your Son on high,
offering him to the world with open arms in a gesture of love.
Help Catholics always to be credible witnesses to this love,
ever clinging to the rock of Peter on which the Church is built.
Mother of China and all Asia, pray for us, now and for ever. Amen!
