The level of seizures, which has not previously been reported, reflects how a policy intended to heap pressure on Beijing over its Uyghur detention camps in Xinjiang risks slowing the Biden administration's efforts to decarbonize the U.S. power sector to fight climate change.Three industry sources with knowledge of the matter, however, told Reuters the detained products include panels and polysilicon cells likely amounting to up to 1 gigawatt of capacity and primarily made by three Chinese manufacturers - Longi Green Energy Technology Co Ltd (601012.SS), Trina Solar Co Ltd (688599.SS) and JinkoSolar Holding Co (JKS.N).Chinese foreign ministry spokesperson Zhao Lijian told a regular news briefing on Friday that claims about the use of forced labor in Xinjiang were "the lie of the century fabricated by a small group of anti-China individuals" and would hinder the global response to climate change.In an email, Jinko said it is working with CBP on documentation proving its supplies are not linked to forced labor and is "confident the shipments will be admitted."The UFLPA essentially presumes that all goods from Xinjiang are made with forced labor and requires producers to show sourcing documentation of imported equipment back to the raw material to prove otherwise before imports can be cleared."
