Sorry about splitting up your post, but I could see no other way of handling it.
What do you think that the round earth model appeared in history?
ancient Greek? or Medieval?
Late Ancient Greek period.
In Asia, China Korea and Japan etc, I know that Jesuit gave the notion.
We Asian thought that the Earth is flat until then.
Yes, that would be right. I believe it was in the 17th century AD.
When did the Vatican start to believe the Round Earth?
although Bible says flat Earth.
The "The Vatican" never "believed" in the flat earth, though the shape of earth was never a part of Church Doctrine.
The
earth's being stationary and at the
centre of the Universe was, however, certainly an "Article of Faith".
You have pointed an interesting issue.
The main problem is Vatikan's try to support the globist theory. Normally a religious structure does not change its mind by easy. What did happen to change their mind?
The Vatican never changed their mind of the matter of the shape of the earth.
The Church never "officially" taught that the earth was flat.
Look at the writings of:
the early
English monk, theologian and historian, the Venerable Bede (673–735) and
the
monk John of Sacrobosco (c. 1195–c. 1256) who wrote the
Treatise on the Sphere.

The flat earth myth
. . . . . .
flat-earth belief was extremely rare in the Church. The flat earth’s two main proponents were obscure figures named Lactantius (c. 240 – c. 320) and Cosmas Indicopleustes (6th century; the last name means “voyager to India”). However, they were hugely outweighed by tens of thousands of Christian theologians, poets, artists, scientists, and rulers who unambiguously affirmed that the earth was round. Russell documents accounts supporting earth’s sphericity from numerous medieval church scholars such as friar Roger Bacon (1220–1292), inventor of spectacles; leading medieval scientists such as John Buridan (1301–1358) and Nicholas Oresme (1320–1382); the monk John of Sacrobosco (c. 1195–c. 1256) who wrote Treatise on the Sphere, and many more.

One of the best-known proponents of a globe-shaped earth was the early English monk, theologian and historian, the Venerable Bede (673–735), who popularized the common BC/AD dating system. Less well known was that he was also a leading astronomer of his day.

Here is what Bede said about the shape of the earth—round “like a ball” not “like a shield”:
“We call the earth a globe, not as if the shape of a sphere were expressed in the diversity of plains and mountains, but because, if all things are included in the outline, the earth’s circumference will represent the figure of a perfect globe. … For truly it is an orb placed in the centre of the universe; in its width it is like a circle, and not circular like a shield but rather like a ball, and it extends from its centre with perfect roundness on all sides.”
More in The flat earth myth.
Not only that, but the "shape of the earth" was
never an "article of faith" with the Roman Catholic Church and in the first few centuries there were those who followed the Hebrew tradition of the flat domed earth but most followed the Greek idea of the Globe earth.
What
The Church did object to was not the earth being a Globe but with the Copernican idea the earth was not the centre of the universe.
