Not sure your points are valid when you chose to simply not buy actual facts because these facts go against your claims. Im not a greens supporter and couldn't really care what China do with regards to emissions / smog control. It is however happening and it will impact on what previously was considered the best way to process.

The following is a cut out from the press late 2016

"Oct 15 China's Hebei province, the country's biggest steelmaking region, has imposed what it calls "special emission restrictions" on local mills as part of its war on smog, according to a policy document.
Local steel enterprises will have until Sept. 1, 2017, to ensure their facilities comply with tough new standards for sulphur dioxide and other major sources of air pollution, the local environmental protection bureau said in a notice.
Hebei is responsible for nearly a quarter of China's total national steel output. It was the location of seven of China's 10 smoggiest cities last year and is a major source of air pollution in China's capital, Beijing.
The province has pledged to shut 60 million tonnes of crude steelmaking capacity and 40 million tonnes of coal production capacity from 2014 to 2017."
