Chung also worked to normalize relations between the two Koreas. In 1998, at the age of 82, he worked with the South Korean government to provide economic assistance to the North. President Kim wanted to provide a $100 million donation as a way to jump-start economic development in North Korea. However, Kim could not find a legal way to transfer the funds. He turned to Chung, who was already negotiating a large program with the North. Kim persuaded Chung to increase his investment by $100 million with money from secret loans provided by the government-controlled Korea Development Bank. The historic South-North summit took place, with Chung traveling across the border in a motorcade of cars containing some 1001 "unification cows" as a gift to the North Korean people.
