The Sino-Vietnamese relationship is characterized by asymmetry, yet Vietnam’s post-Cold War foreign policy towards China encompasses three paradigms: (a) internal and external balancing against China, (b) greater international integration to prevent political and economic dependence on China and (c) ‘cooperation’ with China on mutual interests while ‘struggling’ against China’s encroachment on Vietnam’s sovereignty. The ongoing dispute in the South China Sea presents a primary security concern for Vietnam as well as a challenge to its bilateral relations with China, particularly as maritime tensions provoke nationalist and anti-China protests among the Vietnamese public. This article presents an analysis of anti-China protests in Vietnam that resulted from South China Sea tensions between 2007 and 2017 in order to examine whether the protests—which are rare in Vietnam—had any effect on Vietnam’s foreign policy towards China. The findings reveal that the protests did not result in a change in Vietnam’s foreign policy towards China both during the maritime crises or in the long term.

Abstract In the South China Sea dispute, some Track-2 settings, along with Track-1 efforts by ASEAN and China, have facilitated some conflict “management.” But they have not brought about conflict “resolution” of the basic sovereignty and control issues. Conflict “irresolution” has ensued instead. Short-term balancing may perhaps generate long-term socialization convergence.

China’s growing assertiveness in the South China Sea (SCS) has long been recognized and considered as a big threat to regional peace and stability. Such perversity has triggered territorial and overlapping claim disputes among countries in the region, including Vietnam, a neck-to-neck neighbor with China. Despite all possible efforts, the stagnation of Vietnam’s resolution to deal with this matter in recent years has been problematic which raises the authors’ concern about the potential effective response that Hanoi might take in resolving the complexity of the dispute. Firstly, it is important to understand Vietnam’s interests in the SCS and its long-term stance in the area. Secondly, to explain the modest action of Vietnam towards China in the SCS, it is key to realize its undeniable economic reliance on this powerful neighbor. Meanwhile, China has continuously posed its massive power over Vietnam’s Sea territory which threatened its security. Hence, the readers can understand the intricate relationship that Vietnam is tied up in. Besides this, the authors also analyze the current maritime diplomacy that is pursued by Vietnam along with its effectiveness which becomes the foundation for suggesting the future strategies of Vietnam based on internal balancing and multidirectionalism in its foreign policy.

Abstract In recent years, long-term, high-resolution records from the deep sea and ice-cores have offered new research opportunities for Quaternary science. Paleoclimate studies are no longer restricted to individual glacial cycles, but extend to long-term (≥105 yr) processes across those cycles. Ocean Drilling Program Leg 184 of the South China Sea in 1999 uncovered well-preserved sediment sections, in which three long-term cycles in Pleistocene carbon isotope (δ13C) sequence have been found and demonstrated to be common in the global ocean. Subsequent discoveries confirm the existence of long-term processes of 105 yr in both the hydrologic (ice-sheet changes) and carbon (biogeochemical changes) cycles, posing the question whether the two processes are related. The present review shows that the long-eccentricity cycles prevail throughout the δ13C and other biogeochemical records in geologic history, and 400-kyr cycles in the oceanic δ13C sequence before the Quaternary can be hypothetically explained by changes in ratio between particulate and dissolved organic carbon (POC/DOC) in the ocean, depending on the monsoon-controlled nutrient supply. This is a ‘DOC hypothesis’. However, ocean restructuring at 1.6 Ma marked by the isolation of a sluggish abyss under the Southern Ocean has obscured the long-eccentricity 400-kyr signal in oceanic δ13C. The last million-year period has experienced two major changes in the climate regime, namely the mid-Pleistocene transition (MPT) centered at 0.9 Ma and the mid-Brunhes event (MBE) around 0.4 Ma. The MPT and MBE were preluded by δ13C maxima-III (δ13Cmax-III) ∼ 1.0 Ma and δ13Cmax-II ∼ 0.5 Ma, respectively. Together with similar hydroclimatic phenomena over corresponding glacial cycles, the two groups of hydrologic and biogeochemical events appear to have been driven largely by oceanographic changes in the Southern Ocean. Therefore, we interpret that the long-term biogeochemical processes originating from the Southern Ocean must have played a crucial role in Quaternary ice-sheet waxing and waning.
