Joe Biden has promised to crack down on China’s coal power spree in other countries if elected U.S. president in 2020.
In a detailed climate manifesto  published last Tuesday , the front-runner in the U.S. Democratic primaries said he would “lead a major diplomatic push to raise the ambitions of countries’ climate targets”.

The platform combines support for poor countries with tougher accountability for polluters, singling out China’s foreign investment program for scrutiny.
“China is far and away the largest emitter of carbon in the world, and through its massive belt and road initiative, Beijing is also annually financing billions of dollars of dirty fossil fuel energy projects across Asia and beyond,” the manifesto said.
“Biden will rally a united front of nations to hold China accountable to high environmental standards in its belt and road initiative infrastructure projects, so that China can’t outsource pollution to other countries .”
The carbon footprint of China’s coal deals abroad threatens to overwhelm its domestic efforts to curb emissions. At the latest belt and road summit in April, Chinese firms inked new coal deals  while president Xi Jinping said the initiative “aims to promote green development”.
Engagement with China would form part of a global push to ban fossil fuel subsidies by the end of Biden’s first term, he said. The U.S. would axe its own support for dirty energy exports and instead promote clean technology.
The former vice president under Barack Obama also recalled U.S. financial obligations to support poorer countries in tackling climate change. President Donald Trump has reneged on US$2 billion owing to the Green Climate Fund (GCF). Biden would “recommit” to the fund, although he did not specify whether that meant increasing the U.S. contribution in the ongoing replenishment drive.
Climate change has become a flagship issue in the Democratic race, with New York congresswoman Alexandra Ocasio-Cortez and the Sunrise Movement demonstrating mass public appeal for action.
Candidates are competing to answer Ocasio-Cortez’ call for a “green new deal ” of mass public investment in climate action. Massachusetts Senator Elizabeth Warren has pitched a $2-trillion package  to develop climate-friendly industries, while Washington Governor Jay Inslee aims to “catalyze” $9 trillion. Biden’s headline figure is $5 trillion, with $1.7 trillion to come from federal sources.
Alongside Biden, Inslee has one of the most fleshed-out plans  for international climate diplomacy. It goes further on climate finance, pledging to double the U.S. contribution to the GCF.
Ocasio-Cortez has called Inslee’s plan the “gold standard” —but Inslee is an outsider in a crowded field.Biden last month characterized his climate stance  as a “middle ground ” between environmentalists and blue-collar voters, to the ire of climate hawks. The details released on Tuesday attracted more favourable reviews  from activists.
