Vietnam may not have a legal framework to regulate offshore wind farms until next year, a delay that could deter billions of dollars in foreign investment in the industry. The World Bank Group estimates the industry could add at least $50 billion to its economy. Approval of a draft power development plan in December targeting 7 gigawatts of offshore wind capacity by 2030 has been repeatedly delayed. EU companies are pushing for rapid regulatory progress, but Vietnam is also keen to scrutinize Chinese investment for national security reasons. Some believe pilot projects can be approved quickly, even before legislation is passed, while others believe wind turbine makers are unlikely to review investment plans given Vietnam's geography and influence as a regional manufacturing powerhouse.
