One of USA President Franklin Delano Roosevelt's socialist programs or pogroms after the government's depression of 1929, followed by WWII is shown in the amazing photo of Americans of Japanese descent performing the early American stiff-arm salute (the origin of the Nazi salute) inside an internment camp in the USA (It lets you know how late the American Nazi salute was being used in the USA). http://rexcurry.net/pledgeofallegiance-japanese.jpg
The photo is on the page http://rexcurry.net/pledgesalute.html
A different photograph is often seen that is a poignant image of Japanese-American children saying the pledge of allegiance (with the hand-over-the heart) soon after President Franklin Delano Roosevelt ordered the relocation of 120,000 Japanese-Americans into internment camps in the West (said hand-over-the-heart photo is by Dorothea Lange). The people who display Lange's hand-over-the-heart pic never show the stiff-armed salute photograph of Japanese-Americans (or any Americans) and never mention Dr. Rex Curry's work showing that it was the origin of the Hitler salute/Nazi salute under the National Socialist German Workers Party. Part of the reason is a media cover-up of the early pledge history, and part of the reason is sheer ignorance of the Pledge of Allegiance caused by government schools (socialist schools) that in turn cover-up the pledge's putrid past. http://rexcurry.net/pledgesalute.html
Lange also photographed Thomas Cave with his social security number tattooed to his arm during the government's depression in 1939 (the year that the National Socialist German Workers Party joined as allies with the Union of Soviet Socialist Republics in a pact to divide up Europe and both invaded Poland et cetera).
Lange, a photographer working for the ominously titled Resettlement Administration (RA), had previously worked for FERA (forerunner of today's FEMA) and later the FSA, took the picture of the socialist slave number under the auspices of the USDA. Before the New Deal, government was much smaller, and, saving the USDA, these "alphabetics" (as they were also called) did not exist. http://rexcurry.net/tattoos.html
Government in the USA subjected many people of many cultures to military socialism and taught them to perform the early American stiff-arm salute (adopted later by the National Socialist German Workers Party). Some societies are still performing the early American straight-arm salute, as shown in more photographs.
The stiff-arm salute in the United States was also adopted as the official Olympic salute and spread internationally. See http://rexcurry.net/bookchapter1a1c.html
Americans of Japanese descent were exposed to the early American stiff-armed salute in government schools (socialist schools) and at internment camps. The following photograph shows an internment camp in the U.S. with Americans of Japanese descent. http://rexcurry.net/pledgeofallegiance-japanese.jpg
Japan still uses the American salute as shown in a video on Youtube.com with the ignorant title "Nazi..er, Roman Salute @ Sports Day"

Do you possibly have any information about:
* WHEN the Chinese adopted the salute? I have not certainty about this as it is difficult to research Chinese history about things like that at that time. My theory is that they picked it up via the "young pioneers" (the children's group that is shown in some of the photos) and Mao picked up that group and its American nazi style salute from Stalin under Soviet socialism, where they also had the "young pioneers" (the Young Pioneers are similar to Hitler Youth). Thus, the salute ultimately came from the USA for all countries via American socialists to German socialists, Soviet socialists, and Chinese socialists.
Cuba appears to have also copied the Soviet Socialist "young pioneers" and uses the same gesture
* What do they use it for? meaning: What are they soluting? if you mean the chinese then I think it is for their flag and also an accompanying song. There is a film called "vote for me" (that streams over the web via Netflix) and it shows children doing the salute and singing the song at the same time. Part of that song is written in this photo that is taken from the film "vote for me"

* When they use this solute in China, it is likely, that they call it "their own/original invention"? Yes, that is likely. That is also what German socialists said under Hitler. Both China and Cuba would have a hard time denying that they probably picked it up from the Soviet Socialists via the "Young Pioneers."
Isn’t it sick to realize that when German socialists and Soviet Socialists were allies (and before) in 1939, they were both doing the “Nazi salute” which was made in the USA?
Many people are also unaware of Hitler's involvement with Soviet socialism via the Bavarian Soviet Republic or Munich Soviet Republic.

The Soviet Socialist young pioneers seem to have begun before Hitler Youth. Both were imitations of Boy Scouts that pre-dated both in both countries and that were replaced by the government imitations. So the gesture came from the USA via the boy scouts who were doing it in the USA every day in government schools and traveling internationally to scout excursions. http://rexcurry.net/pledge-of-allegiance-scouting.html
It was also borrowed from the USA as the official Olympic salute.
Your quote about the "military mind" is interesting in light of the fact that the nazi salute came from the military salute being used in the USA's Pledge of Allegiance. Francis Bellamy and Edward Bellamy touted "military socialism" because they loved the military and want the military system to be imposed on all of society via the government schools.
