Aug 27 (Reuters) -ICE cotton futures fell for the second consecutive session on Tuesday, pressured by demand concerns due to escalating U.S.-China tensions, while downbeat sentiment in the oil, grains and broader financial markets added to the pressure.

* Cotton contract for December CTZ4 fell 0.34 cent, or 0.48%, at 69.92 cents per lb at 11:40 a.m. EDT(1540 GMT).

* "There was little anxiety when the U.S. put sanctions on some Chinese companies, so China came out with an angry response that may have bent cotton a little bit lower today," said Keith Brown, principal at cotton broker Keith Brown and Co in Georgia.

* China called U.S. sanctions on its entities over the Ukraine war "illegal and unilateral" and "not based on facts" in comments on Tuesday ahead of White House National Security Adviser Jake Sullivan's arrival in Beijing for days of high-level talks.
