Toshiyuki,
 a
 Japanese scholar, wrote an article on Khaidu's war with the Yuan.'4 Liu
Ying-shen is currently the most active researcher on the Yuan's relations with the
Central Asian khanates and has written several articles on the subject, comparing the
Chinese and the Persian sources." The lengthy articles by Saguchi Toru, the senior
Japanese Mongolist, on the 1303 peace and on later Yuan relations with the western
khanates, published in 1942, still are useful in regard to the Yuan's post-1303
relations with the western khanates.'

 and

 Dardess wrote an interesting and well-
researched article on the limitations of the Yuan's efforts to control Mongolia and
Central Asia from distant China, attributing the loss of Central Asia in the late
1320s to what he calls "spatial limitations."'

shu sheng), which was established by Khaishan to increase the state's revenue, was
the subject of a monograph by the Japanese scholar Aoyama Koryo.'
