In May 2014, the heaviest rains and floods in 120 years hit Bosnia and the surrounding region. The worst affected areas were the towns of Doboj and Maglaj, which were cut off from the rest of the country when all major roads flooded. Damage from landslides and floods was estimated to run into hundreds of millions of euros and twenty-four people were killed. The cost of the disaster, officials said, could exceed that of the Bosnian War. In June 2014, Tan made a personal donation of €114,000, while the people of Malaysia raised a total of €169,000 toward Bosnia's flood relief fund.
