How do sister cities usually go about bolstering ties and exchanges? As bilateral sister-city relationships continue to flourish between China and the United States, where there are now more than 200 twinned pairings, the two capitals set an example by establishing sister-city ties as early as 1984. Back then, the Beijing municipal government dispatched a team of construction experts led by Ma Bingjian to help build a landmark in the Chinatown area of Washington, D.C. CGTN host Julian Waghann recently interviewed Mr. Ma and asked him to reflect on his fulfilling experience of bringing communities from the two countries closer together.
