Can China still promote a man who campaigned against corruption while family accumulated 100s of millions of dollars?

Can the Communist Party of China still promote a man who campaigned against corruption while his family accumulated hundreds of millions of dollars"

Probably. There's likely too much at stake to alter the long-planned transition of power at this late hour. The party's leaders proved long ago that they put "stability" ahead of all other principles.

Part of the problem is there is likely no one in the leadership group who is any cleaner than Mr. Xi.

Investigative Report on Colossal Wealth of Family of China's President Designate

"Xi Jinping Millionaire Relations Reveal Fortunes of Elite"

Xi Jinping, the man in line to be China's next president, warned
officials on a 2004 anti-graft conference call: "Rein in your
spouses, children, relatives, friends and staff, and vow not to use
power for personal gain."

As Xi climbed the Communist Party ranks, his extended family
expanded their business interests to include minerals, real estate
and mobile-phone equipment, according to public documents compiled
by Bloomberg.

Those interests include investments in companies with total assets
of $376 million; an 18 percent indirect stake in a rare- earths
company with $1.73 billion in assets; and a $20.2 million holding
in a publicly traded technology company.

Let Me Try a Prediction About Canadian Politics For a Change

Well so far I am unable to come up with much informed speculation on what will happen at upcoming Chinese Communist Party 18th Congress. I only have wishful thinking on that one.

But I am pretty sure that I won't be wrong again with this Canadian political prediction:
If Trudeau junior becomes leader of the Liberal Party, that Party will go the way of the other rock solid national institutions of my youth --- the Progressive Conservative Party, Eaton's stores and Bell Canada --- in short order.

I should just stick with Chinese political prognoses, I suppose.

The lawmakers asked both companies if they have "ever been ordered by the Chinese government to perform a task or seek information on behalf of the government""

They also asked the companies if any employees "ever attempted to obtain private information from an individual, company or government" through their company's network or equipment.
