TAIPEI -- Taiwanese President Tsai Ing-wen toured NASA's Johnson Space Center in Houston, Texas, on Sunday, becoming the island's first sitting leader to set foot in an American government facility in the U.S.
The visit, highlighting the close ties between Taiwan and the U.S., appears aimed at checking China's efforts to absorb the island. Although China has yet to react officially to Tsai's visit, it may have a vociferous response.
