South Korean foreign policymakers are perplexed over a report published by the U.S. Congressional Research Service that carries China’s flawed perspective on the history of Northeast Asia.

A first draft of a historical report from the CRS on the history of the Korean Peninsula was found stating that the Korean kingdoms of Goguryeo and Balhae were regional minority kingdoms that belonged to China’s imperial Tang Dynasty.

The report also states that the Tang Dynasty ruled the region north of the Han River after the Goguryeo Kingdom had fallen.

It also carries China’s current perspective that a stone monument on Baekdu Mountain bears evidence to the fact that the Joseon Dynasty and the Qin Dynasty designated the Tumen and Yalu Rivers to serve as the border between the Korean Peninsula and China.

The report is being written at the behest of the foreign policy committee of the Senate and is scheduled to be released mid-November.

Seoul has requested the offending parts in the report be edited, and the CRS has reportedly sent an answer that South Korea’s perspective could also be included in the final publication.
