President Donald Trump talks to reporters as he departs on travel to Argentina from the White House in Washington, November 29, 2018.

President Donald Trump's willingness to intervene in the case against Huawei Technologies CFO Meng Wanzhou appears to be part of a larger White House effort to close a trade deal with China and boost the stock market.

Reports circulated this week, primarily off an interview the president gave to Reuters, that Trump was willing to step into the Meng case if it would resolve an ongoing dispute with China over tariffs or contribute to national security.

The statement came days after The Wall Street Journal quoted sources close to Trump as saying he is watching the stock market closely and has become increasingly concerned that the trade battle he has initiated with China is taking its toll on Wall Street.

"If I think it's good for the country, if I think it's good for what will be certainly the largest trade deal ever made — which is a very important thing — what's good for national security — I would certainly intervene if I thought it was necessary," Trump told the wire service Tuesday.
