<span>On June 25, 1950, the Korean War began when some 75,000 soldiers from the North Korean People’s Army poured across the 38th parallel, the boundary between the Soviet-backed Democratic People’s Republic of Korea to the north and the pro-Western Republic of Korea to the south. This invasion was the first military action of the Cold War. By July, American troops had entered the war on South Korea’s behalf. As far as American officials were concerned, it was a war against the forces of international communism itself. After some early back-and-forth across the 38th parallel, the fighting stalled and casualties mounted with nothing to show for them. Meanwhile, American officials worked anxiously to fashion some sort of armistice with the North Koreans.

China entity sponsored commercial expeditions in the Indian ocean in ships known as junks.
The Indian Ocean has been strategically located at the tip of the sea since ancient times, and its long coastline is the longest of any country on the Indian Ocean's rim, hence the name India.
This ocean occupies a unique place because of its features. As mentioned in Indian Ocean Facts, the water here has the highest concentration of dissolved and suspended hydrocarbons, the most negative water balance, and the highest and lowest salinity of any single water source.
City-states traded gold, ivory, and iron with landlocked kingdoms such as Greater Zimbabwe. These materials were sold to India, Southeast Asia, China, and elsewhere. These were African exports in the Indian Ocean trade. These items were in short supply in Asian countries and could be sold at a profit.
