The people of the island of New Guinea traded with China and the Malay empire, the latter of which was Muslim, beginning in the 16th century. In 1988, Muslims in Papua New Guinea set up the first Islamic center, with the help of a Malaysia-based Islamic organisation and the Saudi Ministry of Islamic affairs. In 1996, three more Islamic centers were established, with the help of the Muslim World League. There are now seven Islamic centers in the nation. The first mosque, known as the Baitul Kareem Mosque, was built in 1988 in Kimbe, New Britain, by the Ahmadiyya Muslims.
