The United States and China have agreed on establishing a marine protected area in the Ross Sea of the Antarctic.
US Secretary of State John Kerry said Wednesday the agreement was made to preserve "one of the world's last remaining pristine marine environments."
Kerry made the remarks at a joint press conference with Chinese State Councilor Yang Jiechi following a two-day strategic dialogue between the two countries in Washington.
The world’s largest economies indicated a stronger cooperation in regard to tackling the climate change and other environmental issues.
"It's particularly important that we are doing this now with respect to the oceans because we haven't agreed on every aspect of maritime policy, but it indicates that we're working hard to address differences and to find the areas of commonality," Kerry said.
The amount of plastic being dumped in the ocean, the illegal use of high seas drift net for fishing, and the greenhouse gas role in acidification of oceans were among other topics discussed.
"We need to share our experience, realize complementarity and leave future generations with a blue ocean and a blue sky," Yang said.
Kerry warned that there could be one ton of plastic in the oceans for every three tons of fish by 2025.
Yang and two Chinese vice premiers - Liu Yandong and Wang Yang - have also met with other high-ranking officials from the United States, including President Barack Obama and Vice President Joe Biden.
The dialogue was held despite a rift between Beijing and Washington over a hack in the Office of Personnel Management, which the US blames on China.
Beijing, however, has dismissed the accusations as "irresponsible and unscientific".
The development came ahead of a visit by Chinese President Xi Jinping to the US in September.
