This is a rough translation from the Nov 5 Gaceta that mentions a temporary replacement for Khan while out of the country to China Nov 2-10. I typed this into a google translator so it may not be completely accurate:

Article 1. Named manager of the Ministry of People's Power for Basic Industries and Mining, the citizen Jesus Enrique Paredes Rosales, head of the Identity Card No. V-3114641, during the temporary absence of the proprietor, who traveled to the PRC on official business.
