For an audience that Chen obtained with Pope Benedict XVI in December of 2007, Franz worked with the National Palace Museum in Taipei to transfer an image of Cherry Tree and Grosbeaks, a Qing court painting in the museum's collection by Giuseppe Castiglione (1688-1766), onto a vase, which was given to the pope. It was a successful instance of aesthetic diplomacy.
2007 年 12 月，陳立恒獲梵蒂岡教宗本篤 16 世接見，他帶著法藍瓷與台北故宮合作、將清朝義大利籍畫家郎世寧畫作「櫻桃嬉春」轉製的立體瓷瓶送給教宗，是一次成功的藝術外交。
