Rubio said the U.S. deployment of military assets and provision of $37 million in aid demonstrated the importance of the U.S. staying internationally engaged.
Senior State Department official Scot Marciel declined to comment on the Chinese response. But he said the U.S. aid effort has reinforced in the minds of Filipinos that the U.S. is "a long-time and good partner that they can depend on," and demonstrated to the wider region the "unmatched" logistical capabilities of the U.S. military.
"I think that's gone widely noticed," Marciel told the hearing.
At the weekend, China said it was monitoring conditions in the Philippines, and was ready to send rescue and medical teams "should conditions permit." It was unclear whether the Philippine government had accepted the offer.
Views expressed on the Chinese Internet have argued strongly against aiding the Philippines, despite the potential damage to China's hopes of being regarded as a responsible regional and possibly global leader.
