Israelites built the great temples and empires of China, Japan, Thailand, etc., similar to the genocide of our ancestors in modern day America, Israelites in Asia were genocided in subsequent wars and had their existence hidden.
That being said there are many men & women in Thailand, Cambodia, Japan, etc. that are descendants of Israelites, even though they look like the heathen.
Psalms 83:5 | 2For, lo, thine enemies make a tumult: and they that hate thee have lifted up the head. 3They have taken crafty counsel against thy people, and consulted against thy hidden ones. 4They have said, Come, and let us cut them off from being a nation; that the name of Israel may be no more in remembrance. 5For they have consulted together with one consent: they are confederate against thee: 6The tabernacles of Edom, and the Ishmaelites; of Moab, and the Hagarenes; 7Gebal, and Ammon, and Amalek; the Philistines with the inhabitants of Tyre; 8Assur also is joined with them: they have holpen the children of Lot. Selah.
Ezekiel 36:17 | Son of man, when the house of Israel dwelt in their own land, they defiled it by their own way and by their doings: their way was before me as the uncleanness of a removed woman. 18Wherefore I poured my fury upon them for the blood that they had shed upon the land, and for their idols wherewith they had polluted it: 19And I scattered them among the heathen, and they were dispersed through the countries: according to their way and according to their doings I judged them. 20And when they entered unto the heathen, whither they went, they profaned my holy name, when they said to them, These are the people of the LORD, and are gone forth out of his land. 21But I had pity for mine holy name, which the house of Israel had profaned among the heathen, whither they went. 22Therefore say unto the house of Israel, Thus saith the Lord GOD; I do not this for your sakes, O house of Israel, but for mine holy name’s sake, which ye have profaned among the heathen, whither ye went.
