In early 2001, ground was broken for the construction of several additional churches on a parcel of land in Jebel Ali donated by the government of Dubai to four Protestant congregations and a Roman Catholic congregation. Construction on the first Greek Orthodox Church in Dubai (to be called St. Mary's) began at the end of 2005. The land for the construction of the church was also donated by the government to the Greek Orthodox community of Dubai.
Financial support to non-Muslim groups from the Dubai government comes in the form of donated land for the construction of churches and other religious facilities, including cemeteries. They are permitted to raise money from among their congregants and to receive financial support from abroad. Christian churches are permitted to openly advertise church functions
They definitely hate Israel if not all Jews, and have a bit of a slavery problem. That's why there were no high level visits to Dubai when W was pushing the ports deal.
