Stadium diplomacy
Stadium diplomacy is the construction of stadiums and sports facilities in other nations as a form of foreign aid with implementation also supporting the overseas expansion of donor-country construction contractors.
China is the most prominent practitioner of this strategy, using it as a form of soft power to bolster diplomatic ties. The practice dates back to at least 1958, when China funded the National Sports Stadium in Mongolia. The method contrasts from other methods such as stadium subsidy which uses taxpayers money and gives it to the private sector to manage the facility and profit.
