Bloomberg reports that the company’s new Vietnam campus is being built by China State Construction Engineering Corp. (CSCEC), a state-owned contractor the US Department of Defense identifies as a Chinese military-linked enterprise. Hunan provincial officials have also listed the project as a key annual investment, heightening sensitivities as the US considers blocking TP-Link products from the American market.
