Geneva, Feb 16 : New World Trade Organization (WTO) chief Ngozi Okonjo-Iweala has vowed to tackle her top priorities of fighting against the Covid-19 pandemic and promoting the free flow of vaccines and medical supplies, breaking the logjam in the dispute settlement mechanism and reaching a deal to cut fisheries subsidies. Nigeria's Okonjo-Iweala was formally appointed on Monday as the seventh director-general of the WTO. She is the first woman and the first African to be chosen as director-general of the 26-year-old global trade body, Xinhua news agency reported. She has promised deep and wide-ranging reforms in her first virtual press conference following the appointment by consensus during the WTO's General Council. "We have the twin shocks of the pandemic, the health side and the economic side, which is challenging so many and it has brought economic devastation to many parts of the world," she told reporters. "The WTO at this point in time is facing so many challenges. It cannot be business as usual at the WTO. "We also have the issue of lack of trust which has built up over time, not just between the US and China but also between developing and developed country members," she said. Listing her top priorities, the former Nigerian finance minister and World Bank veteran said: "First and foremost, we need to focus on the issue of Covid-19 and what the WTO can do to contribute to solutions. It needs to work with the WHO, with the COVAX Facility, with the ACT Accelerator, all these organizations that are trying to accelerate supplies and vaccines to poor countries." She said that the WTO could work with members to lift export restrictions to facilitate the free flow of vaccines and medical supplies. Okonjo-Iweala previously chaired the board of Gavi, the Vaccine Alliance, which works with the World Health Organisation (WHO) on the COVAX initiative for equitable global access to Covid-19 vaccines in poorer countries. "Covid-19 is an opportunity for the WTO to have a success and show what it can do, both in the short term and in the long term." The director-general designate said the WTO and its members could encourage countries to lift export restrictions in a bid to ensure the free flow of medical commodities, stressing that "vaccine nationalism does not pay". "Secondly, how can we encourage and find a third way in which vaccines can be manufactured in many more countries, whilst we don't discourage research and innovation." /IANS
