How much of that 2.4m tonnes comes from other countries though? And the other countries know that it's not getting recycled properly yet still send it over to offload their guilt.
Also you can't just use raw numbers as the population numbers are completely different. Waste generated per capita (excluding and import/export) would be a more accurate metric.
None, at the moment, considering China just instituted a plastic waste import ban.
But you're still implying that people are sending it to China in order to alleviate themselves of guilt, without China's consent. That's crap. They were conducting waste/recycling operations for business. If you agree to send plastic waste to China, then it's on China NOT to chuck the plastic in a river. Just because they're negligent doesn't make you liable.
My cynical take is that these kinds of articles are cooked up in major polluters PR departments. It's classic misdirection, and we seem to fall for it every time.
Also how countries are still delivering their waste to there knowingly(!) that it has a high chance of reaching the ocean. They want to get rid of it for the lowest cost and then blame the other country for not following through.
"91% of potentially recyclable plastic ends up in landfills, or worse, in oceans."
So right there, no ratio. How much goes into the landfill and how much into the ocean? Because lets face it:
Landfill>Ocean
For comparison, 8m tonnes of plastic ends up in the ocean annually according to the cited 2015 UCSB study: http://www.news.ucsb.edu/2015/014985/ocean-plastic
That's 8m tonnes globally. The US makes about 30m tonnes a year. What's the US' share of plastic in the ocean?

About 340 tonnes a year. Yeah, that's a lot, but that's 0.00425% of the total. We're in 20th place.
China drops 2.4m tonnes a year. About 30% of all the plastic waste that goes into the ocean each year.
Article does nothing to point out the plastic waste just getting chucked into rivers in India and Asia.
