Kim Jong Un has condemned the use and consumption of imported goods, calling it a "disease" that must be eradicated. The North Korean leader made the statement at the seventh assembly of the General Federation of Trade Unions of Korea Tuesday, just days after reports surfaced that he was gaining weight because of his excessive consumption of French wine and Swiss cheese.

North Korean workers must "uphold the honor of the fatherland and the know-how of the people, and with pride and courage make with their own hands products better than [other countries], thereby eradicating the disease of imports," Kim Jong Un wrote in a letter titled "The contemporary mission of the working class of Kim Il Sung-Kim Jong Il," state-controlled news agency KCNA reported Thursday.

Kim ordered the country to put self-reliance first in order to resist imported goods, according to South Korean news agency Yonhap.

"[Workers must] carry with them a firm belief in their own strength, raise high the spirit of self-reliance and struggle, and achieve the nationalization of raw materials, production technology while boldly modernizing production processes in order to create the highest level of socialist civilization," he stated.

Recently, South Korea's National Intelligence Service (NIS) reportedly said during a parliamentary briefing that Kim's health has not improved since July, and he currently weighs 290 pounds.

Kim's weight gain started since he fully assumed power in 2012, following his father's death in December 2011. At the time, Kim reportedly weighed 200 pounds.

In April, Kim reportedly boasted about his consumption of "10 bottles of Bordeaux" in a single day to the family's former sushi chef Kenji Fujimoto.
