Additionally, in August 2014 business organizations representing South Korea's and Japan's largest companies announced there was a "need to raise public interest for the undersea tunnel plan that could link South Korea to Japan by rail", as well as increasing tourism between the countries. Representatives of the Federation of Korean Industries and Nippon Keidanren stated that increased tourism between their two lands could "help overcome past differences and help fuel domestic spending in both countries", while the proposed undersea tunnel could create ₩54 trillion won (54T원, or US$53 billion) in economic benefits. It could provide about 45,000 jobs, according to the Busan Development Institute.
