A week later, Mongolia began talks in Seoul about bringing home the last law code of the Yuan dynasty.

What did the Vatican give Mongolia?
The Vatican gave Mongolia copies, not originals, of 38 documents from the 13th and 14th centuries. Montsame reported on 28 October 2026 that Ambassador Gerelmaa Davaasuren received them from Paolo Vian, Prefect of the Vatican Apostolic Archives, and Mauro Mantovani, Prefect of the Vatican Apostolic Library.
The set covers both sides of the exchange. It includes Pope Innocent IV's official letter of 1245 to the Great Khan, letters from Güyük Khan to Innocent IV, Pope Nicholas III's correspondence of 1278 with Khubilai Khan, diplomatic letters exchanged with Abaga Khan and Argun Khan of the Ilkhanate and their families, letters to and from the Mongol commander Baiju, and the instructions and credentials given to papal envoys travelling into Mongol lands.
What do the Mongol Empire Vatican letters say?
The best-known letter is a demand, not a greeting. The Asnad.org digital Persian archive, hosted by the Chair of Iranian Studies at the University of Bamberg, dates Güyük Khan's reply to between 2 and 11 November 1246. It is written in Persian ta'liq script.
Güyük handed the letter to the papal envoy Giovanni da Pian del Carpine. In it, the Khan calls on the Pope and the rulers of Europe to come to his court and swear allegiance, and stresses his own superior position. It answered Innocent IV's letter of 1245, which AsiaNews also lists among the key sources on the period.
Why is this happening now?
The handover follows an agreement signed on 4 December 2025 between the Chinggis Khaan National Museum and the Vatican Apostolic Library, during President Khurelsukh Ukhnaa's state visit. The museum's report says it covers scholar exchanges on Mongol Empire history, manuscripts, archives and joint research.
Montsame's "This Week in Mongolia" listed an international conference, "Diplomatic Policy of the Great Mongol Empire: History and Modern Times", at the Chinggis Khaan National Museum on 28 October 2026. The two sides also discussed cataloguing and digitising other Mongolian items in the Vatican Library, including Mongolian-script manuscripts and rare books in Mongolian and Kalmyk.
What is the Yuan law code that Mongolia wants from Korea?
It is the Zhizheng Tiaoge, the Statutes of the Zhizheng Era, the last legal code of the Yuan dynasty. Montsame reported on 4 November 2026 that Mongolia's Ambassador to South Korea, Sukhbold Sukhee, visited the Jangseogak Archives of the Academy of Korean Studies on 3 November and discussed bringing the document to Mongolia and opening it to scholars and the public.
The code was compiled in November 1345 under Emperor Toghon Temür and came into force in 1346. The only surviving physical copy was found in 2003 in a family archive in Gyeongju. No date has been announced for any transfer.
Where can you see Mongol Empire history in Mongolia?
The Chinggis Khaan National Museum in central Ulaanbaatar is the place to start. Neither the Vatican nor the museum has said whether the new copies will go on display, so treat them as a research collection for now. According to the museum's visit page (read 5 November 2026), winter hours from 15 September to 14 May are 09:00–17:00 with last entry at 16:00. The same page also mentions a Tuesday closure in winter, so check before you go. English-language guided tours must be booked by phone.
Out in the Orkhon Valley, UNESCO's Orkhon Valley Cultural Landscape page describes Kharkhorum as the 13th- and 14th-century capital of Chinggis Khaan's empire, established in 1220, and Erdene Zuu as the earliest surviving Mongol Buddhist monastery. See our guide to Ulaanbaatar's history museums and the new Kharkhorum city plans.
