I want to know the answer to the following question:
Along with the Mongolian People's Republic and the People's Republic of China, what country did the RSFSR border to its southeast?
All the background I'm provided with is that "Within the Soviet Union, the RSFSR bordered the Ukrainian, Belarusian, Estonian, Latvian and Lithuanian SSRs to its west and Azerbaijan, Georgian and Kazakh SSRs to the south.". Is that enough to answer the question?
Answer: no
