== Proposition of dividing in sectors == 
 History of Manchuria is very rich but also complicated to better understand its history i suggest to divide that region in six sectors have a look at  map 1  map 2 and map 3  
 * Inner Manchuria (4 sectors)  
 :The "western" border of Inner Manchuria now incorporated in Inner Mongolia 
 ::- the former Xingan/ Hsingan Province (興安)  
 ::- the former Rehe Province (热河/熱河) and Liaobei/Liaopei 

 :The "southern" part of Inner Manchuria  the Liao river bank (with Liaodong peninsula), corresponding roughly to the former Liaoning province including  
 :: - former Jinzhou (锦州/錦州) located the right bank the Liao river 
 :: - former Fengtian (奉天) located on the bank the Liao river 

 :The "eastern" part of Manchuria bordering Korean peninsula, corresponding roughly to the actual Jilin Province  southern part of the Sungari basin contain also the banks of Yalu river , the banks of Tuman river and including the Changbai Mountain (Kaema Plateau) 
 :: - former Antung (安東) 
 :: - Kirin (吉林) 
 :: - and Sunkiang/Songjiang (松江) or Binjiang (濱江) 
 :: - parts of North Korea above the Goryeo Cheolli Jangseong (northern part of North Pyongan, Jagang, Ryanggang, North Hamgyong and South Hamgyong provinces) 

 : The "northen" part of Inner Manchuria 
 :: - Nunkiang/Nenjiang (嫩江) 
 :: - Hokiang/Hejiang or Sanjiang (三江) 
 :: - former Heilongjiang (黑龍江) 

 * Outer Manchuria (2 sectors) corresponding to well defined at the Nerchinsk Treaty: 
 : -  the actual Primorye/Primorskii Krai ceded by China to Russia in 1860 
 : -  the southern part of Khabarovsk Krai  ceded by China to Russia in 1858 including  
 :: - Bikinsky District 
 :: - Vyazemsky District 
 :: - Lazo District 
 :: - Khabarovsky District  
 :: - and eventually Nanaysky District because Nanai peoples are also Tungusic peoples. 

 Conclusion  
 :::The western part of Manchuria history is closely related to China and Mongolia HIstory 
 :::The eastern part of Manchuria and the actual Primorye/Primorskii Krai is closely related to Korean History although not necessarily included. 
 :::The northern part of Manchuria with the southern part of Khabarovsk Krai  are closely related to the Black River Mohe history, the ancestor of the Wild Jurchen and the Nanai peoples. 
 :: I also emit some reserve concerning Rehe and Xingan province, because i consider that the border of Manchuria / East Tartary are  
 :::- on the West  Liao River (see Goguryeo Cheolli Jangseong) and the Greater Khingan Range 
 :::- on the South: Goryeo Cheolli Jangseong and Liaodong peninsula 
 :::- on the north  Stanovoy Range or Outer Khingan Range 
 :::- on the east  Sakhalin Island and Sea of Japan (East Sea)
