Understanding the U.S.–Vietnam Security Relationship, 2011–2017
Dang Cam Tu,Hang Thi Thuy Nguyen 한국국방연구원 2019 The Korean Journal of Defense Analysis Vol.31 No.1
This paper seeks to explore the new dynamics of U.S.–Vietnam security relations from 2011 to 2017. It begins with a review of the attempts before 2011 to establish a foundation for a normal security relationship between the United States and Vietnam, and progresses in the scope and pace of the bilateral relationship in this field. The paper then examines the process of a deepening security relationship between the two countries from 2011 to 2017, focusing on the motivations for increased security cooperation and the developments in five main areas of cooperation, namely maritime security, high-level dialogues, search and rescue, humanitarian assistance and disaster relief, and peacekeeping operations. Finally, this paper looks at the potential and limits of the U.S.–Vietnam security relationship, analyzing the possibilities for building a more balanced and effective security relationship and the limitations of U.S.–Vietnam security cooperation. In conclusion, the authors argue that the years from 2011 to 2017 witnessed new and positive moves in the U.S.–Vietnam security relationship. This is a highly signicant development for Vietnam and the United States and an illustration of the fast geostrategic change underway in the Asia–Pacic region in the post–Cold War.

α-calcium sulfate hemihydrate (α-HH) was synthesized by salt solution methods to prepare a promising biomaterial for bone tissue repair and regeneration. The successful synthesis of α-HH was evaluated by field emission scanning electron microscopy (FE-SEM), thermogravimetric analysis (TGA), X-ray diffraction (XRD), and Fourier transform infrared (FTIR) scanning. The sterility of α-HH before and after irradiation with gamma ray was firstly confirmed by Colonies Forming Units (CFU) counting assay, to target the surgical grade application. In vitro tetrazolium bromide (MTT) assay, crystal violet (CV) and acridine orange (AO) staining was performed to assess the initial cytotoxicity and cell attachment ability of α-HH. Further in vivo implantation into rabbit distal femoral condyles defect exhibited the ability of salt solution-synthesized α-HH to promote the localization of osteocytes and osteoblasts, which improve the bone tissue repair and regeneration. The findings suggested that α-calcium sulfate hemihydrate synthesized by salt solution method is a potential material that can be used as bone substitutes.
