Overview
Dang Thi Hoang Yen is a Vietnamese businesswoman, born in 1959, who founded the company that became Tan Tao Investment and Industry Corporation (ITA) in 1993 and has chaired it since (Nhà Đầu Tư). Vietnamese business press reports that she is the sister of Dang Thanh Tam, the chairman of Kinh Bac City Development Holding Corporation and Saigontel, and that her company’s fortunes have risen and fallen alongside his over the same decade (Dân Trí). She briefly served as a National Assembly delegate before being removed from that role in 2012 under circumstances that official and personal accounts describe very differently, and she later filed international arbitration claims against the Vietnamese government worth billions of dollars.
Business career
Nhà Đầu Tư’s business reporting describes Tan Tao Investment and Industry Corporation, founded by Dang in 1993, as growing into a major Vietnamese industrial park and real estate developer, with projects including a planned $6.7 billion thermal power and deep-water port complex at Kien Luong, the 1,200-billion-dong Vina Universal Paradise commercial complex in Quang Ngai province, and the 9,600-hectare Xuan Mai new urban area project in the former Ha Tay province. VietnamNet reported that, as of December 2021, her Tan Tao shareholding was worth about VND725.6 billion, ranking her 185th among the wealthiest shareholders on Vietnam’s stock exchanges, after ITA shares rose 243% between July and early December that year (VietnamNet).
National Assembly removal, 2012
Dang was elected as a National Assembly delegate for the Duc Hoa constituency in Long An province in 2011, per Nhà Đầu Tư’s reporting. VnExpress reported that in May 2012, the National Assembly’s Standing Committee found she had submitted dishonest information in her candidacy file — including failing to disclose the date of her Communist Party membership and an outstanding arrest warrant against her husband — and that she submitted a resignation letter shortly before the full National Assembly voted, with more than 90% approval, to formally remove her as a delegate on May 26, 2012 (VnExpress).
Dang’s own account, reported by VOA Tiếng Việt, differs sharply: she says no official explanation was ever given for her removal, and attributes it to her public advocacy for constitutional reform, multi-party democracy and anti-corruption measures, including opposition to figures linked to then-Prime Minister Nguyen Tan Dung (VOA Tiếng Việt).
International arbitration claims
VOA Tiếng Việt reported that in 2019, under the name Maya Dangelas, Dang and her U.S.-registered companies filed an international arbitration claim seeking more than $2.5 billion in damages, alleging that the Vietnamese government unlawfully terminated a contract for a thermal power plant and deep-water port project at Kien Luong after demanding the project’s structure be changed and then removing it from the national power development plan; the outlet reported that a Paris arbitration tribunal had ordered Vietnam to pay litigation costs to her company as of July 2022, though it did not report a ruling on the underlying claim itself. A July 2022 press release from her legal team stated that Tan Tao Investment and Industry Corporation, under her chairmanship, filed a second arbitration claim on July 5, 2022 under the U.S.-Vietnam Trade Relations Agreement, seeking $1 billion in damages over Vietnamese court bankruptcy proceedings against the company that she characterized as retaliatory (GlobeNewswire press release).
What this profile does not claim
This profile does not resolve the conflict between the official Vietnamese account of her 2012 National Assembly removal and her own account of it; both are stated above as reported. It does not state a founding date for her company with certainty, since independent Vietnamese press reporting (1993) conflicts with a 2022 press release from her own legal team (1996). It does not report an outcome, on the merits, for either her 2019 or 2022 international arbitration claims, as no independently reported source read addresses one. It does not state her current place of residence or citizenship status, and it does not cover the internal operations, other shareholders or full project history of Tan Tao Investment and Industry Corporation beyond what is described above.

What we could not verify
These claims came up in research and could not be confirmed. They are recorded here rather than published as fact or quietly dropped. If you hold a source that settles one, please tell us.
- Sources give conflicting reasons for her 2012 removal from the National Assembly. VnExpress and Nhadautu, reporting the official account, attribute it to the Standing Committee's finding of dishonest candidacy disclosures. VOA Tieng Viet's reporting on her own account states she was given no official explanation and that she attributes the removal to retaliation for her public advocacy on constitutional reform and against corruption. This profile presents both accounts without resolving the discrepancy.
- Sources also conflict on when her company was founded: VnExpress and Nhadautu report 1993, while a 2022 GlobeNewswire press release from her own legal team states ITACO was founded in 1996. This profile uses the independently reported 1993 date in its facts and timeline and flags the discrepancy here rather than adopting the first-party figure.
- No independently reported source read confirms the outcome, on the merits, of either her 2019 or 2022 international arbitration claims; VOA Tieng Viet reported only that a Paris arbitration tribunal had ordered Vietnam to pay litigation costs to her company as of July 2022, a procedural ruling distinct from a decision on the underlying claims. This profile does not state that either claim succeeded or failed.
- No independently reported source read gives a specific, current place of residence for her; this profile does not assert one.
