"We continue to closely monitor China's military developments and to encourage China to exhibit greater transparency with respect to its capabilities and intentions," State Department spokesperson Jen Psaki said.
"We aren't going to analyse or comment on what every release means," Psaki said when asked about China revealing its first fleet of submarines for the first time in 42 years.
"We remain committed to building stable, reliable, and continuous military-to-military relations with China," she added.
"That's the message we would send to both sides. We continue to work with China on military-to-military relations and continue to encourage them to be transparent," Psaki told reporters in response to a question.
