AbstractThis paper presents a novel approach to cross-cultural AI negotiation agents to facilitate cross-cultural conflict resolution. In multi-party negotiations across different cultural value dimensions, we develop a multi-layered architecture composed of cultural value dimensions, negotiation strategies, and ethical reasoning, which can mediate complex negotiations. Specifically for negotiating with others, we propose a combination of LLMs and symbolic reasoning capabilities to recognize and change accordingly to cultural nuances in the negotiation contexts. We do that through simulated case studies of three different cultural contexts in territorial and resource disputes and show that our system is effective. This shows that culturally aware AI negotiation agents can solve 72% of the scenarios that fail to achieve agreement using only 43% less negotiation timeframes than traditional diplomatic approaches. We explore the implications for international relations, the ethical considerations, and avenues for future research directed at developing AI mediators for complex geopolitical conflicts.
