Vietnam said on Thursday that military drills conducted this week by Beijing in the South China Sea will hurt negotiations on a regional maritime code of conduct (COC) for the disputed waters. The exercises could complicate efforts to restart talks on a long-awaited code between China and the Association of Southeast Asian Nations ( Asean ), foreign ministry spokeswoman Le Thi Thu Hang told a regular briefing. China on Monday began five military exercises simultaneously along different parts of its coast, including two exercises near Paracel Islands which are also claimed by Vietnam. China holds drills near disputed Paracels for a third time this year “The resumption of code of conduct (COC) negotiations after a long pause because of the [coronavirus] pandemic is the priority of Asean countries and China ,” Hang said. Vietnam shared that priority and “looks forward to “concluding the COC in an effective, comprehensive way”, in line with international law, Hang said. Earlier this week, Vietnam’s President Nguyen Phu Trong spoke to China’s President Xi Jinping , calling for talks on the competing claims to the South China Sea and suggesting that the two countries should “work together to address their existing problems, especially on maritime issues”, according to Vietnamese newspaper Nhan Dan . China, which has for years been locked in maritime disputes with other coastal states in the South China Sea, has in recent months boosted its presence and held exercises in disputed parts of the strategic waterway, at a time when other claimants are battling coronavirus outbreaks. The United States has accused China of bullying its neighbours, while Beijing says Washington and its Western allies have been interfering and endangering security by sending naval vessels to the region. In August, Vietnam said the presence of Chinese bombers on the Paracel Islands “jeopardises peace”. Explainer | Why are tensions running high in the South China Sea dispute? Hang said on Thursday that Vietnam demanded that China respect its sovereignty and does not repeat such drills in the area. The COC has been a stated goal of Asean and China for nearly two decades, but regional security experts have questioned China’s sincerity towards concluding it and doubted whether a legally binding agreement can be forged.
