^^You're right. Maybe we should also be cautious in interpreting the issue because we might just be making a big fuss out of it. We might be misinterpreting the treaty itself.
By the way, such is also prohibited under Philippine Laws specifically R.A. 6969 or Toxic Substance and Hazardous and Nuclear Waste Act of 1990. According to the news, it prohibits the entry of hazardous waste into and their disposal within the country for whatever purpose, including transit.
Anyway, the Senate would have to ratify the treaty first.
