Hello, this is Kenji from Hong Kong. Normally at this time of year, the city would be preparing to mark the anniversary of the Tiananmen Square crackdown on pro-democracy protesters that took place on June 4, 1989. But Beijing's tightening control of the city means that for a third year in a row, no major commemorations are being planned.
Another date involving the Chinese military, however, is also coming up: On Friday, a U.S. ban on investment in companies linked to China's armed forces is set to take full effect. Thirty-three years on from Tiananmen, it is another reminder of how the U.S. is still grappling with its relationship with Asia's leading economy.
