China is telling the U.S.to stop sending American ships and military aircraft close to islands that Beijing claims in the South China Sea.
Addressing a joint press conference here on Friday, Chinese State Councilor Yang Jiechi said, "According to the U.S".
A "frank" exchange of views can be expected in top-level diplomatic and security talks between the United States and China on Friday, including on issues such as human rights and the South China Sea, the USA ambassador to China said.
Trump's administration has also accused China of interfering in USA politics, charges China strongly denies, and the two have sparred over the disputed South China Sea and self-ruled Taiwan, which China claims.
Mattis made clear that this demand go unheeded by Washington, which insists it is acting under worldwide law to preserve access for it and others to the South China Sea.
Despite the airing of grievances, the talks appeared aimed at controlling the damage to relations that has worsened in recent months and at paving the way for an encounter between U.S. President Donald Trump and Chinese President Xi Jinping at the Group of 20 summit in Argentina at the end of November. He added that the USA was looking to achieve progress on North Korea, discuss strategic security and reduce fentanyl imports to the US.
The U.S. defense chief also said the two sides had "discussed the importance for all military, law enforcement, and civilian vessels and aircraft, including those in the PLA Navy, the Chinese Coast Guard, and the PRC Maritime Militia, to operate in a safe and professional manner, in accordance with worldwide law, as we seek peaceful resolution of all disputes in the South China Sea".
But Wei and Mattis agreed on the need to lower U.S.
"Even as the two countries (US and China) confront important differences in the bilateral relationship, their cooperation remains essential on many, many central issues", Mr. Pompeo said. China will stick to a path of peaceful growth and of constructively developing its relationship with the US based on the principles of mutual respect and mutual benefit, the president said.
During Friday's dialogue, USA officials also reaffirmed "strong ties" with Taiwan, which has been self-ruled since the 1940s but claimed by China.
Defense Secretary Jim Mattis said the talks were "candid" but that the two militaries looked to improve communication and avoid "miscalculation" at sea. "We pressed China to live up to its past commitments in this area".
China and the United States have slapped tariffs on hundreds of billions of dollars of each other's goods, jolting global financial markets, and Trump has threatened to set tariffs on the remainder of China's $500 billion-plus exports to the United States if the trade dispute can not be resolved.
China and the US are now locked in an ongoing trade war as each country has introduced tariffs on goods traded between each other.
Mattis did meet Wei in Singapore on 18 October and told him that the world's two largest economies needed to deepen high-level ties to reduce the risk of conflict. "Their top priority is to stabilize relations", she said. He signed the Taiwan Travel Act earlier this year, which encourages visits "at all levels" between USA and Taiwanese officials.
Yang on Friday noted the Chinese government attaches great importance to social and economic development in Xinjiang and Tibet and has taken a host of measures to promote stability, "unity" and people's well-being there.
Yang said that China, North Korea's main lifeline, would enforce United Nations sanctions but voiced hope that Washington and Pyongyang "will meet each other halfway" and "accommodate each other's legitimate concerns".
