Peppered?

Hello, I encountered this phrase while looking at the Economist Weekly published the day before yesterday.

—The congress will be peppered with signs of Mr Xi’s power—

"The congress will be peppered with signs of Mr Xi’s power and his determination to flaunt it. These may be evident in tweaks to the party’s charter that delegates will endorse. Details of these have not been revealed, but they may include the shortening of the umbrella term for his political thinking from the wordy “Xi Jinping Thought on Socialism with Chinese Characteristics for a New Era” to the snappier “Xi Jinping Thought”. That would equate him with Mao."

I took this to mean something like to "be permeated," but I'm not sure whether that's right.
