Researchers and practitioners in business and diplomacy explore how multinational corporations can use diplomacy to help them deal with challenges in the international business arena. Their topics include business diplomacy in implementing the global 2030 development agenda: core competencies needed at the corporate and managerial levels, business diplomacy in emerging markets: the intersection of roles between states and multinationals, the ethics and business diplomacy of multinational company tax avoidance, the legitimacy of state ownership in foreign direct investments by emerging economic firms, and corporate diplomacy and institutional upheaval in host countries: the "Arab Spring" experience of two Canadian multinationals in Egypt.
