Chinese fishing boats are known to intrude on international waters and use controversial methods that harm the environment and deprive locals of their livelihoods.
The Chinese companies have not lived up to their contracted responsibilities, despite being paid 8.5 times the previous rate. Piles of garbage on sides of roads are now commonplace.
A new study suggests the coal projects backed by China could lead to 30,000 air pollution-related deaths and 20,000 cases of child asthma.
The project has hired more than 500,000 citizens who lost their jobs because of the coronavirus pandemic.
The Chinese are getting rid of their dirtiest industries and installing them in countries like Pakistan where people are most vulnerable to pollution and climate change, observers say.
The Khyber Pakhtunkhwa Forest Department will distribute and plant 150,000 trees during this campaign.
Officials are seeking to bolster fish populations, thus aiding the cause of food security and reducing discontent that can breed militancy.
A government ban on traditional brick kilns through December has workers concerned for their future as officials search for alternative technologies.
Under the project, launched by Prime Minister Imran Khan, about 5.4 million trees are expected to be planted each day across Pakistan for the next five years.
The cleanup is aimed at reducing pollution in Pakistan, including in the air and water, and at providing a clean and green country to future generations.
