[200.205, 200.340] To Whom it May Concern: I am an Assistant Professor in Energy Materials I am writing in my personal capacity to oppose the proposed revisions to sections 200.202(e) and 200.220 that would restrict international scientific collaboration and isolate American scientists. Many international collaborations with leading researchers from across the globe; UK, Japan, France, Germany, Ireland, Canada, China, Spain... These have led to major scientific breakthroughs (such as the achievement of world-record solar cell efficiencies) CERN as the obvious one. Many world-leading scientific facilities reside outside the US. Goodwill and collaboration are key to ensuring the US remains at the forefront of global science – China is catching up by being more open to collaboration Depends on the country. There are good people and excellent scientists in countries like China and Russia, who do not support the regime and whose collaborative research efforts benefit humanity. Of course, care should be taken that collaboration is not deceptively used for nefarious purposes (e.g. weapons), but blanket bans are silly This rule will further damage the US position as the global leader in science, pushing global partners to collaborate with China and other adversaries.
