Bill Gates, on China trip, lauds free trade and talks futuristic toilets

US billionaire philanthropist Bill Gates unveiled on Tuesday a futuristic toilet that doesn't need water or sewers and uses chemicals to turn human waste into fertilizer. The Microsoft co-founder also lauded the globalised and free trade systems that made the toilet technology possible. His trip comes amid trade tension between China and the United States, the world's two largest economies, which have slapped tit-for-tat tariffs on goods worth billions of dollars.
