WASHINGTON, May 4 (Reuters) - Philippines President Ferdinand Marcos Jr said on Thursday that granting U.S. access to Philippine military bases was a defensive step that would be "useful" if China attacked Taiwan. Marcos told Reuters the Enhanced Defense Cooperation Agreement (EDCA) reached with the United States in 2014 was originally conceived to improve disaster responses. Marcos said Washington "has not proposed any kind of action for the Philippines in terms of taking part in the defense of Taiwan." Biden said on Monday that the U.S. commitment to the defense of its ally was "ironclad," including in the South China Sea, and that the guidelines issued on Wednesday laid out treaty commitments if either side were attacked in the South China Sea. He said the patrols would help preserve freedom of navigation in the South China Sea, where China has a growing military presence.
