China must keep up efforts to "revolutionise" its toilets until the task is completed, state media quoted Chinese President Xi Jinping as saying on Monday, amid efforts to boost the domestic tourist industry and improve the quality of life.
Xi launched the "toilet revolution" in 2015 as part of a drive to improve standards of domestic tourism in China, which he said suffers from deep-seated problems of a lack of civility.
"The toilet issue is no small thing, it's an important aspect of building civilised cities and countryside," Xi said, according to the official Xinhua news agency.
As an emerging industry, Chinese tourism needs an upgrade in both hardware and software to continue strong growth, Xinhua reported Xi as saying.
China's National Tourism Administration recently announced plans to build and upgrade 64,000 toilets between 2018 and 2020.
But the toilet revolution is about more than just giving sightseers a better holiday experience; it is also about creating a more civilised society, Xinhua added.
