The outsourcing of emissions hit it's peak at the beginning of 2008. Then the financial crisis hits and the outsourcing of emissions decreased significantly. Currently, China is responsible for their own emissions which is the result of domestic growth and in particular the construction sector.

Similarly, we can argue that "the east" had outsourced emissions in the 1950s to the 1990s to "the west" since the manufacturing happened in "the west". In fact, China's rapid growth was made possible by western companies and products, yet this isn't accounted for today as well.

In reality the outsourcing of emissions is way to complex to attribute it to actual policy making or distribution of emissions on a global level.

Edit, added source:

> That said, these transfers only account for a fraction of the rise in developing country emissions. Which makes sense. In China, roughly 87 percent of the steel and 99 percent of the cement produced is consumed domestically.
