The Open Door Policy is a name in foreign affairs preeminent
used to stand to the US policy set up in the late nineteenth century and the beginning
of twentieth century, as articulated in Secretary of State John Feed's Open Door
Note, dated September 6, 1899 and exchange to the significant European forces.
The open door policy meant all nations were to have equal access in trading with China - but Japan wanted to dominate in the region. In 1931, Japan invaded and occupied Manchuria, the northeastern region of China. The invasion followed an explosion that blew up a portion of railroad tracks near the city of Mukden. (Thus it became known as "The Mukden Incident.") The railway was owned by the Japanese, who had invested in development in the region. Japan blamed Chinese nationalists for the explosion, but others thought the bombing may have been done by Japanese military personnel to provide Japan with an excuse for invading and occupying Manchurian territory. The Japanese declared the region to be a new country, independent of China. which the Japanese called Manchuko. In reality, the territory was not independent but was controlled by the occupying Japanese army.
The League of Nations condemned Japan in 1933 for the events in Manchuria, but that did little to stop Japan. Japan withdrew from the League of Nations at that time, and by 1937 began further invasions into Chinese territory. and in the early 1940s Japan occupied French Indochina (territory in Southeast Asia).
There is still enough air-pressure inside Mark Watney's suit even though it was compromised because of the presence of huge amount of air in the suit of Mark Watney. When he tear his suit in order to move upward to reach his crew member, the suit lost some amount of air but not all the air is lost so we can say that there is still enough air pressure present inside Mark Watney's suit.
