protect the financial system and we want to use our scale and global footprint to make a positive contribution to fighting financial crime in the economies and communities where we live and work. HSBC is a strong proponent of publicprivate partnerships and informationsharing initiatives, and we play an active role in such partnerships globally.

Having been involved in the creation of a similar PPP in the UK back in 2015 and having seen its success year-on-year, I have high hopes for the UAE’S PPP, and I am honoured to be part of it. The UAE joins the growing list of PPPS created in major financial centres such as the USA, UK, Hong Kong, Singapore etc. The UAE’S PPP committee consists of very knowledgeable and experienced members from across the sectors. Working together, we shall undoubted make the UAE an even safer place to do business."

Pope Francis speaks to the Roma community in the Lunik IX district in Košice, Slovakia, on Sept. 14, 2021. /

he spoke about Jesus’ words in the Gospel of Matthew: “Do not judge.”“the Gospel must not be sweetened up or watered down. Do not judge, Christ tells us,” he said. “How often are our judgements really prejudices, pre-judgements? How often do we rest content with labels. In this way, we disfigure by our words the beauty of the children of God, who are our brothers and sisters.”“our knowledge and appreciation of others,” he added, “must be grounded in our acknowledgement that each of them possesses the inviolable beauty of a son or daughter of God, a reflection of the Creator’s image.”in the Lunik IX district, the Salesian community consecrated a Catholic Church, the Church of the Risen Christ, in 2010, and since 2012 have operated a youth center. The Catholic sisters run a center for women and a kindergarten.in a video the Salesians published earlier this month about their work in the district, Fr. Peter Bešenyei said their service in the community is “always about relationships. Once a relationship is established, mutual prejudices are broken down.”“we Salesians offer immediacy, friendship. Simply, as people, we enter the Roma community,” Bešenyei continued. “Many people ask us: ‘How can we help you?’ I always answer: ‘Come and join us for Sunday Mass.’ The more we isolate ourselves, the more tensions and prejudices will grow. On the contrary, the more we live common positive experiences, the closer we will get.”pope Francis said: “Dear brothers and sisters, all too often you have been the object of prejudice and harsh judgements, discriminatory stereotypes, defamatory words and gestures. As a result, we are all poorer, poorer in humanity.”“restoring dignity means passing from prejudice to dialogue, from introspection to integration,” he continued, explaining that this can be carried out through concern, pastoral care, patience, and concrete efforts. “All these things will bear fruit,” he underlined. “Not immediately, but in due time those fruits will be seen.”košice, with a population of around 240,000, is the second largest city in Slovakia after the capital of Bratislava. It is the largest city on the country’s less-developed eastern side.a new mural was created for Pope Francis’ visit to the Lunik IX district depicting flowers growing from the cracks of a building.

Andrea Gagliarducci/cnamayor Jaroslav Polaček told local media the city of Košice also funded some repairs in the neighborhood prior to the pope’s visit, “so that we are not ashamed of the city quarter because many visitors will come here,” adding that “other special requests, which came directly from the Vatican,” were not completed however.“it is not easy to leave prejudice behind, even for Christians,” the pope said in Lunik. “It is not easy to value others, especially if we see them as problems or enemies; if we pass judgement without making any effort to get to know them and to listen to their stories.”“marginalizing others accomplishes nothing. Segregating ourselves and other people eventually leads to anger,” he stated.“the path to peaceful coexistence is integration: an organic, gradual and vital process that starts with coming to know one another, then patiently grows, keeping its gaze fixed on the future. And what is the future? It is our children. The future belongs to them; they are the ones to guide us: their great dreams must not collide with barriers that we have erected.”“courageousdecisionsmust be made on behalf of our children: to promote their dignity, to educate them in such a way that they can grow up solidly grounded in their own identity and be given every opportunity they desire.”at the beginning of the encounter, Pope Francis listened to two short testimonies from Roma.the 61-yearold Ján Hero, a father of five with his wife, Beáta, who is Slovak, recalled visiting Rome six years ago with other Roma for a meeting with Pope Francis.“we have the hope that your mission here today, among us, in this place will help us to ignite a greater faith and a more stable determination to transform our personal and spiritual life towards the better,” he said.rené Harakaly, 29, grew up in the Lunik IX neighborhood along with her husband Nikola. She said thanks to the help of the Catholic Church and the Salesians, they lived their adolescence “in a more beautiful and meaningful way.”“dedicated themselves to us, they trusted us, and this has influenced our desire for education, even though this was often difficult,” she said. “Our parents also encouraged us to go against the grain.”harakaly said she and her husband received the sacraments from the Salesians, who also baptized their two young children, and with their support, have managed to move to a new part of the city to better integrate into Slovakian society.nikola and René Harakaly, former residents of the Linuk IX district, and their two sons spoke to Pope Francis on Sept. 14, 2021. Vatican Mediafr. Bešenyei, who is the director of the diocesan center for the Roma mission in Košice, told Pope Francis “the Catholic Church is very committed to the Roma, even if by the State this commitment of the Church is ignored and not appreciated.”“holy Father, we believe that his presence in this place contributes to us all achieving greater unity despite diversity and walking the path towards a more peaceful coexistence, through mutual esteem, reconciliation and forgiveness,” he said. Pope Francis concluded the meeting by leading everyone in praying the Our Father.“i ask all of you to overcome your fears and to leave behind past injuries, confidently, step by step: in honest work, in the dignity born of earning our daily bread, in fostering mutual trust and in praying for one another,” he said. “That is what guides our steps and gives us strength. I encourage you, I bless you and I bring you the embrace of the whole
