MOTTO: WITHOUT HELPERS THERE IS NO PEACE (based on Sun Tzu's following quote "If you do not seek out allies and helpers then you will be isolated and weak")

I. Overview

The PPDU was formed in January 31st, 2037 as a transformation of the existing Quadrilateral Security Dialogue consisting of Japan, India, Australia, and the United States. Also known as Asian NATO and in South East Asia, second SEATO, the US soon decided to take the backseat role thanks to the changing security needs in Asia-Pacific after the annexation of North Korea and the end of Indonesian Civil War, along with a new Detente policy with China and Russia.

The re-militarized Japan and the reunited, but still armed to the teeth Korea soon take the lead where the Americans left off and February saw almost the entire South East Asian countries along with New Zealand entered the alliance with exception of Laos and Cambodia which have pro-Chinese governments. Another exception is Mongolia, joined the Vladivostok Pact instead for geopolitical reasons. On the other hand, despite having a socialist government Nepal, home of the Gurkhas, went on to join the PPDU as well. Headquartered in Manila, the alliance then create a partnership scheme to accommodate Western powers with interest in the Indo-Pacific Region; the United States, France, Britain, and Canada along with Taiwan, to the chagrin of the PRC, and in case of Indonesia had often become a subject of debate in its parliamentary commission for defense, intelligence, international relations, and communications with two main factions; "neutral" faction which want to maintain the nation's neutrality along with a closer relation with Eurasian continental powers China and Russia, and the "active" faction which favored the Alliance and more likely to be pro-West.

It's official working languages are English, French (with the insistence of the partner-state France), Chinese (to accommodate the Taiwanese), Japanese, Hindi, and Korean. Indonesian and Malay languages were also widely spoken and considered as de-facto official language as well.
