After the Northeast Project came under strong criticism in 2004, key members of the Northeast Project, along with other academics in Northeast China, founded the journal "History and Geography of Northeast China" (), published by the Jilin Academy of Social Sciences. The journal continued most research formerly conducted by the Northeast Project, and further expanded its research scope to include the historical kingdoms and polities of Lelang Commandery and Silla, both located in the Korean peninsula.
