The top U.S. diplomat for East Asia discussed Middle East developments, the South China Sea and Taiwan issues with Chinese counterparts in Beijing, the State Department said on Monday, the latest effort by the two countries to stabilize rocky ties.

Assistant Secretary of State for East Asian and Pacific Affairs Daniel Kritenbrink met with Executive Vice Foreign Minister Ma Zhaoxu, as well as with Beijing's Taiwan Affairs Office Deputy Director Qiu Kaiming, the State Department said in a statement on the April 14-16 visit.

The officials, including U.S. National Security Council senior director for China and Taiwan Sarah Beran and U.S. Ambassador to China Nicholas Burns, discussed bilateral, regional and global issues, including the Middle East, China's support for Russia's defense industrial base, cross-Strait issues, the South China Sea and North Korea, the department said.

"The visit builds on recent high-level diplomacy with the PRC to manage areas of difference as well as areas of cooperation, while reducing the risk of miscalculation," it said, referring to the People's Republic of China.

The statement gave few details on the talks.

Though U.S. officials say communication channels with Beijing have largely normalized after months of heightened tensions, they have also warned that Chinese support for Russia's war in Ukraine put stabilizing ties at risk.

The meetings come ahead of the May presidential inauguration in democratically governed Taiwan, which Beijing claims as its territory, and after the U.S. held summits last week with both Japan and the Philippines that focused on pushing back against China in the South China Sea and elsewhere.

In meetings with the Philippines, the U.S. reiterated its "ironclad" support for the Philippines amid Manila's maritime dispute with China in the South China Sea, in which there have been several tense run-ins in recent weeks.

Taiwan, China can resolve differences, ex-president says after meeting Xi

Former Taiwanese President Ma Ying-jeou speaks to the media at Taoyuan international airport after concluding his 12-day trip to China in Taoyuan.

Taiwan and China can peacefully resolve their differences, former Taiwan President Ma Ying-jeou said on Thursday after meeting Chinese President Xi Jinping, adding that people on both sides of the Taiwan Strait share the same culture and history.

Ma, president from 2008 to 2016, last year became the first former or sitting Taiwanese leader to visit China.

On Wednesday, he held his second meeting with Xi, following a landmark summit in Singapore in 2015 when Ma was still Taiwan's leader, which was the first time Chinese and Taiwanese leaders had met following the end of the civil war in 1949.

Speaking on his return from Beijing, Ma said he hoped young Taiwanese can put aside ideology and realise the historical and cultural links between Taiwan and China.

"More importantly, the Chinese on both sides of the Strait can handle disputes peacefully," he added.

China considers democratically-governed Taiwan its own territory, and has ramped up military and political pressure to assert those claims. Neither government recognises the other.

Ma, who was accompanied by a group of students to Beijing, said his visit had shown the youth that people on either side of the strait are "descendants of the Yan and Yellow Emperors", an expression referring to a common ancestor.

In an apparent slip up, Ma added that people on either side of the strait both belong to "the Republic of China", before correcting himself to say "the Chinese people", using wording referring to those ethnically or culturally Chinese.

Ma made the same verbal slip up during his meeting with Xi, in footage carried on Taiwanese television stations.

The defeated Republic of China government fled to Taiwan in 1949 after losing a civil war to Mao Zedong's communists.

China's government, formally the People's Republic of China, does not recognise the existence of the Republic of China, Taiwan's official name, making the mention in Xi's presence highly sensitive.

Ma laughed but did not answer the question when asked if this wording was intentional.

Taiwan's government rejects Beijing's sovereignty claims, saying the People's Republic of China has never ruled the island and that only the Taiwanese people can decide their future.

China says its precondition for dialogue is to recognise that both China and Taiwan belong to "one China", which Taiwan President Tsai Ing-wen has refused to do.

Xi told Ma that outside inference could not stop the "family reunion" between the two sides of the Strait, and there were no issues that could not be discussed. He made no mention of using force against Taiwan in his public remarks.

Speaking at a regular news conference in Taipei, Jan Jyh-horng, spokesperson for Taiwan's China-policy making Mainland Affairs Council, said China was to blame for tension in ties with Taiwan.

"It's not us sending military aircraft and ships to harass them everyday," Jan said, referring to China's almost daily military activities around the island.

Ma remains a senior member of Taiwan's main opposition party the Kuomintang (KMT), which in January lost for the third time in a row the presidential election, but has no official party position. The KMT advocates close ties with China and dialogue, but strongly denies being pro-Beijing.
