It is proved that Dokdo is Korean
territory.
According to several historical documents ,
Dokdo was Korean territory since 512.
In
the Annals of the Joseon Dynasty, it is marked that when Isabu occupuied Usanguk in 512, Dokdo was
also incorporated.
lso, Japan
has already agreed that they do
not own Dokdo, Jeju island and Ulleungdo
in 1946, 'Supreme Commander's Memorandum No. 677'.
But after the Korean War they invaded Dokdo
and changed their mind, saying Dokdo is their territory.
Compared to Korea ,Japan does not have the adequate information tho prove it is theirs.
To add, "Dokdo belongs to the Ulleung County
land, and Ulleung Island and a stone blade, Ulleung-gun, (Dokdo)
govern."
This is a part of 'Regulations of the republic of Korea No.41' in
1900 whish is 5years earlier than the Japanese announcement in 1905.
