The European Union on Friday voted to adopt definitive tariffs on China-made electric vehicles. In a recent interview with CGTN's Tian Wei, Ngozi Okonjo-Iweala, the director-general of the World Trade Organization, warned that unilateralism could result in a lose-lose situation, disproportionately affecting poorer nations. She called for greater global cooperation, lauded China's strong support for the multilateral trade system, and stressed that dialogue and negotiation are key to resolving the current global trade disputes.
