Prolific startup accelerator Y Combinator has abandoned plans to establish a branch of the program in China. The company cites a general change in strategy, but a deafening silence on the complexity and controversy of working with China right now suggests there’s more at play.

In a short blog post, YC leadership explained that “as we worked to establish YC China, we had a change in leadership,” viz. the replacement of CEO Sam Altman with Geoff Ralston in May. This apparently led to a complete about-face on YC’s China strategy.
