Washington---US President Barack Obama urged Beijing to take "concrete steps" to ease tensions over cyber intrusions and maritime claims, as America and China wrapped up three days of candid talks.
American officials have voiced deep concerns about both issues at the annual strategic and economic dialogue due to set guidelines for steering future ties.
During talks with officials including Vice Premier Liu Yandong and Vice Premier Wang Yang, Obama "raised ongoing US concerns about China's cyber and maritime behavior, and he urged China to take concrete steps to lower tensions," the White House said in statement.
Ties have strained over US accusations of cyber espionage and this week's talks come after revelations of huge breaches of US government computer networks at the Office of Personnel Management.
US Secretary of State John Kerry, who hosted the talks along with Treasury Secretary Jacob Lew, said cyber hacking raised questions about security and "frankly harmed American businesses."
But even though both sides have stressed they continue to have differences over various issues, they have also been at pains to emphasize that they can cooperate.
Kerry said this, the third round of talks which he has hosted, had been "one of "the most constructive and productive."
"The United States welcomes the emergency of a stable, peaceful and prosperous China" that can take a leading role in global affairs, he said.
Areas where Beijing and Washington can collaborate include on nuclear non-proliferation efforts with Iran and North Korea, as well as in Afghanistan.
Earlier, the two countries also launched a joint initiative to protect the oceans, and vowed to step up efforts to combat illegal wildlife trafficking.
China and the United States are two of the top fishing nations in the world, Kerry said, and also leaders in ocean science.
"We have a real opportunity here to be able to come together... to deal with conserving and protecting the oceans," he said, adding it could be "a centerpiece in the newly defining relationship with China."
China's State Councilor Yang Jiechi agreed, saying the oceans were "a shared homeland of mankind, vital for our survival and development."
