But Chinese FDI, especially in sensitive sectors like energy, does often trigger Congressional hearings, ad hoc resolutions, and calls for tougher CFIUS action. As a result of high-profile Congressional opposition, China’s state-owned energy company CNOOC withdrew its bid for Unocal, an American energy company, in 2005, before a CFIUS review that most likely would have cleared the deal on national-security grounds.
但是，中国FDI，特别是能源等敏感领域的FDI，确实经常会触发国会听证、临时决议和要求CFIUS更加严格的呼声。2005年，由于高规格的国会反对，中国国有企业中海油不得不收回其对美国能源公司优尼科的报价，而此时CFIUS的审查尚未开始（CFIUS的审查很可能会以国家安全原因叫停这笔交易）。中国至今仍将这一幕作为美国不欢迎中国FDI的证据。
