Ed Miliband is expected to block a bid to forbid the government to buy solar panels that are feared with slave labor.
The government is ready to vote against a Lords -amendment to the Great British Energy Bill when it returns to the commons on Tuesday.
The change would prevent tax money from being used to buy products from a company where there was 'credible evidence' of modern slavery in his supply chain.
The move comes in the midst of mounting unrest about China's involvement in the net zero drive, such as the range of wind turbines and solar panels.
In addition to security problems, there have long been around the use of forced Uighur Labor by Beijing.

Last month, colleagues supported the change of traffic with 177 votes to 127, majority 50, despite the fact that the government claimed that there were already sufficient guarantees.
On Friday, Mr. Miliband GB Energy First Project unveiled a £ 180 million investment that installs panels on the roof on 200 school buildings and almost as many NHS sites.
But when he was asked where the solar panels will come from, he admitted that some will come from China, which is responsible for an estimated 80 percent of the total worldwide offer.
When asked why British was not used, Mr. Miliband told LBC Radio: “Our solar panel industry does not have this kind of share in the market.”
When asked if they will come from China or Russia, he said, “Some of them will be, they will come from different countries, but that's why we have to build our domestic industry.”
The change that colleagues in the GB energy bill matched led to a round of parliamentary 'ping-pong', where legislation is made between the two houses until the agreement is reached.
The proposed law would set up a limited company of the state, supported by £ 8.3 billion in public cash, which would be charged with investing in and developing clean energy projects as part of the drive to tackle climate change and achieve the British Net Zero Emissions target.
Human rights campaigner Lord Alton from Liverpool, the independent cross-bencher who defended the amendment, said last month: 'British work will never be able to compete with slave labor or with industries that are highly dependent on cheaper and dirty energy.
He added: “This amendment puts it to parliament,” do we want a slavery -free green transition or are we satisfied to have the objectives of the government achieved through forced labor in a state accused by the House of Commons of Genocide? '
“It should be unthinkable that the UK did so much to end the scourge of slavery all over the world, accepting it today or will be willing to turn products from a state with an imposed system of forced labor.”
But Minister of Energy Fairy Lord Hunt of King's Heath said at the time: “I understand that great British energy would already have a series of aids to identify and tackle the abuse of human rights in his supply chain.”
He added: “With these tools I am insured and self -assured large British energy will not ignore the credible proof of modern slavery and human rights violations.”

Eleanor Lyons, the independent anti-slavery commissioner of the government, posted X to support the amendment last week
Shadow Net Zero Minister Andrew Bowie said The Telegraph: 'This week, the Conservatives Labor will challenge to change the law to ensure that GB Energy cannot offer financial assistance where the proof of modern slavery exists.
“Will Red Ed do the right thing, and come back, or will he go to China Kowtow like his comrade Rachel Reeves?”
Eleanor Lyons, the independent anti-slavery commissioner of the government, posted X: '10 years since the Modern Slavery Act was adopted last week, more victims have been identified than ever before.
“The government must have the large British energy bill changed to protect human rights and reduce the risk of public purchase of goods made by forced labor.”
