Each weekday morning, I cross D.C.’s National Mall and pass a sign on Constitution Avenue bearing an epigram by the U.S. architect Daniel Burnham: Make No Little Plans. And every morning, these words make me think not of Burnham’s 20th century United States, but of 21st century China. That is now where staggering plans are made and funded. Some Chinese plans will improve lives around the world, while others may erode the liberal international order the United States has led since 1945.
