Wumart Stores faces challenges in expanding internationally from China into developed countries due to lacking relationships with foreign governments, weaker bargaining with foreign suppliers, and brands not being as well known overseas. Additionally, Wumart's resources and capabilities are specific to China and developing countries rather than having technical advantages over developed countries. Domestically, Wumart must defend against competitive threats from international retail formats entering China, local imitation, and local competition through maintaining price and quality advantages, updating technology, expanding market share nationally, pursuing potential joint ventures, strengthening private brands, and using promotional advertising.
