Public health officials from 148 countries meet in Bangkok starting Saturday to spur global efforts against smoking. The agenda at the weeklong Convention of Tobacco Control will highlight efforts to curb tobacco advertising and promotion world-wide. Cigarette smuggling and ways to protect people from secondhand smoke will also be discussed. Tobacco is expected to kill 10 million people each year by 2020, with 70 percent of the deaths in developing countries, according to the World Health Organization. «We all know that smoking kills,» Dr. Shigeru Omi, WHO Regional Director for the Western Pacific, said in a statement. «The solution is simple. One hundred percent smoke-free environments. What isn't so simple is overcoming tobacco industry untruths about smoke-free policies.» The developing world is now the tobacco industry's main marketing target. It accounts for half of the world's 1 billion male smokers and 9 percent of its 250 million female smokers, according to WHO. The Chinese are the world's biggest smokers, with their country accounting for 30 percent of the international market for cigarettes. The United States, Russia, Japan and Indonesia are the next-biggest markets.
