GREENVILLE, SOUTH CAROLINA —
U.S. Republican presidential candidate Ben Carson is promising to release documents he says will prove his claim that China is involved in Syria's civil war.
The Obama administration and foreign policy experts maintain there is no evidence supporting Carson's statement.
Carson said on Friday that he's "surprised my sources are better than theirs.'' The 2016 presidential candidate said he would share his documentation with the White House before the weekend is over. He gave no further details.
Carson alleged in Tuesday's GOP debate that Russia, China and "all kinds of factions'' are involved in the Syrian war.
National Security Adviser Susan Rice suggested on Thursday that China could have a diplomatic presence, but said she has "not seen any evidence of Chinese military involvement in Syria.''
