CHina has entirely selfish motives for signing on to this farce of a deal - "developing" countries (China is somehow still consider one) get a buy and can pollute with practically few if any restriction compared to the US and other "developed" nations.. it is a very unfair deal and a direct attempt to weaken the United States (and ultimately this colony we call Canada) by the globalist, anti-American, socialist movement based out of such places as Paris.  It's heart is the UN.   Canada would do itself a huge favour (as in preserving its existence) by following the US lead.  We are  an oil-rich nation whose economy will alway be largely based on the extraction of our God-given natural resources.
