Sorry, I do not have the answer to that exact question, however, I can tell you more about the government and politics. The Chinese have long been merchants in Papua New Guinea. In 2012, despite a refugee crisis at the border of Papua New Guinea and West Papua, the country was steadfast in its support of Indonesia, which promised Papua New Guinea a greater role in ASEAN in the future. 
 The western half of New Guinea forms the Indonesian provinces of Papua and West Papua. The border between Papua New Guinea and Indonesia was confirmed by treaty with Australia before Independence in 1974. The constitutional convention, which prepared the draft constitution, and Australia, the outgoing metropolitan power, had thought that Papua New Guinea would not remain a monarchy. 
 Sorry, I do not know that exact answer, however, I can tell you about their demographics. Non-traditional Christian churches and non-Christian religious groups are active throughout the country. Religious syncretism is high,while many citizens combining their Christian faith with some traditional indigenous religious practices. 
 Is there anything you can tell me about the government and politics? 
 I am not familiar with the tern Commonwealth realm. Can you tell me anything more about it?
