why did the japanese want to take over port moresby
New Guinea campaign The colonial capital of Port Moresby on the south coast of Papua was the strategic key for the Japanese in this area of operations. Capturing it would both neutralize the Allies' principal forward base and serve as a springboard for the invasion of Australia.[9] For the same reasons, General Douglas MacArthur, Supreme Commander Allied Forces South West Pacific Area was determined to hold it. MacArthur was further determined to conquer all of New Guinea in his progress toward the eventual recapture of the Philippines.[10] General Headquarters Southwest Pacific Area Operational Instruction No.7 of 25 May 1942, issued by Commander-Allied-Forces, General Douglas MacArthur, placed all Australian and US Army, Air Force and Navy Forces in the Port Moresby Area under the control of New Guinea Force.[11]
Treaty ports The British established the first treaty ports in China at the conclusion of the First Opium War by the Treaty of Nanking in 1842. As well as ceding the island of Hong Kong to the United Kingdom in perpetuity, the treaty also established five treaty ports at Shanghai, Canton (Guangzhou), Ningpo (Ningbo), Fuchow (Fuzhou), and Amoy (Xiamen). The following year the Chinese and British signed the Treaty of the Bogue, which added provisions for extraterritoriality and most favoured nation status for the latter country. Subsequent negotiations with the Americans (1843 Treaty of Wanghia) and the French (1844 Treaty of Whampoa) led to further concessions for these nations on the same terms as the British.
