Some familiar names can be seen engaged in the kisses. President Barack Obama and Chinese leader Hu Jintao engage in a passionate, Photoshopped lip-lock. Also, Israeli Prime Minister Benjamin Netanyahu and Palestinian President Mahmoud Abbas kiss passionately. And then there’s Pope Benedict XVI and Ahmed Mohamed el-Tayeb (head of the Al-Azhar mosque in Cairo).
This was done with the aim to attract clients and customers. But in the case of Pope and Imam's lip-lock, the catholic Church got infuriated over the image of the Pope. And it resulted in pulling out the image of Pope and the Imam.
