why did many european nations want to control chinese ports and markets
Western imperialism in Asia Before the Industrial Revolution in the mid-to-late 19th century, demand for oriental goods such as (porcelain, silk, spices and tea) remained the driving force behind European imperialism, and (with the important exception of British East India Company rule in India) the European stake in Asia remained confined largely to trading stations and strategic outposts necessary to protect trade. Industrialisation, however, dramatically increased European demand for Asian raw materials; and the severe Long Depression of the 1870s provoked a scramble for new markets for European industrial products and financial services in Africa, the Americas, Eastern Europe, and especially in Asia. This scramble coincided with a new era in global colonial expansion known as "the New Imperialism," which saw a shift in focus from trade and indirect rule to formal colonial control of vast overseas territories ruled as political extensions of their mother countries. Between the 1870s and the beginning of World War I in 1914, the United Kingdom, France, and the Netherlands—the established colonial powers in Asia—added to their empires vast expanses of territory in the Middle East, the Indian Subcontinent, and South East Asia. In the same period, the Empire of Japan, following the Meiji Restoration; the German Empire, following the end of the Franco-Prussian War in 1871; Tsarist Russia; and the United States, following the Spanish–American War in 1898, quickly emerged as new imperial powers in East Asia and in the Pacific Ocean area.
