In the 13th Century, Nicolo Polo (father of Marco Polo) was visiting the court of the grandson of Ghengis Khan - Kublai Khan.
Kublai Khan was the Emperor of China and he had never met Europeans before. He was delighted to meet this visitor from Venice AND he was strongly impressed by the religious faith of this man; therefore, he sent a letter back to Europe urging that some educated men be dispatched to instruct his people in the teachings of Christianity.
But, because of political upheaval and infighting that was taking place in Europe, there was a long delay in anybody coming. In the end, only 2 representatives of Christianity were sent and even they lost heart soon and turned back.
Because of the failure of the church of that day, Kublai Khan turned instead to Buddhism and that has been the predominant religion in the area from that day to this.
