President Biden will meet with President Xi Jinping of China on Saturday during a global summit in Peru, White House officials said Wednesday. The one-on-one meeting will be Mr. Biden’s final opportunity to challenge the Chinese leader directly on hacking, threats against Taiwan, human rights violations and support for Russia’s invasion of Ukraine.

白宫官员周三表示，拜登总统将于周六在秘鲁举行的全球峰会期间会见中国国家主席习近平。这次一对一的会晤将是拜登就黑客攻击、威胁台湾、侵犯人权和支持俄罗斯入侵乌克兰等问题直接挑战中国领导人的最后机会。

It will be the first time the two leaders have met in person since a summit between them in California a year ago. That meeting was described by both sides as the beginning of improved relations after deep tensions following Mr. Biden’s decision in early 2023 to shoot down a Chinese spy balloon that drifted over the United States.

这将是两国领导人自一年前在加州举行峰会以来第一次面对面的会晤。2023年初，拜登决定击落一枚飘浮在美国上空的中国间谍气球后，两国关系陷入紧张，双方都称加州的会晤是两国关系改善的开端。

Administration officials said they expected Mr. Biden to confront Mr. Xi on issues of disagreement, but to also welcome the resumption of direct communications between the two governments, including the militaries. Mr. Biden has sought to stabilize what he has called the most consequential relationship in the world and has encouraged competition, not conflict.

美国政府官员表示，他们预计拜登将就双方存在分歧的问题直面习近平，但也欢迎两国政府恢复直接沟通，包括军方沟通。拜登一直在寻求稳定他所称的世界上最重要的关系，并鼓励竞争，而不是冲突。

But the meeting comes as President-elect Donald J. Trump prepares to take office again, promising a much more aggressive approach to China that includes vast tariffs on Chinese goods headed for the American marketplace. That has left foreign policy analysts to predict a much more volatile period of tension between the two leaders.

但这次会晤正值候任总统特朗普准备再次上任之际，他承诺对中国采取更加激进的措施，包括对进入美国市场的中国商品征收巨额关税。这使得外交政策分析人士预测，两国领导人之间的紧张关系将变得更不稳定。

Mr. Biden will be in Peru for the annual meeting of the leaders of the Asia-Pacific Economic Cooperation forum. He will meet with Mr. Xi before heading to a brief stop in the Amazon and then the Group of 20 summit of world leaders in Rio de Janeiro.

拜登将前往秘鲁出席亚太经济合作组织领导人非正式会议。他将与习近平会面，然后前往亚马孙地区作短暂停留，并参加在里约热内卢举行的20国集团领导人峰会。

White House officials said on Tuesday that Mr. Biden would discuss areas of cooperation that have been successful over the past four years with the Chinese leader.

白宫官员周二表示，拜登将与中国领导人讨论过去四年中取得成功的合作领域。

Those include working together to decrease the flow of fentanyl into the United States and discussions about how to jointly address the benefits and threats of artificial intelligence as it develops rapidly around the world, according to one official who was authorized to speak to reporters on condition of anonymity.

据一名被授权匿名接受记者采访的官员说，其中包括共同努力减少芬太尼流入美国，以及讨论如何共同应对人工智能在世界各地迅速发展带来的好处和威胁。

But the official said that Mr. Biden would also discuss differences between the countries and how to manage them. At the top of that list, the official said, are reports by U.S. intelligence that China is supporting Russia’s defense industrial base. The United States has imposed hundreds of sanctions on China to prevent that support, and Mr. Biden will raise the issue with Mr. Xi, the official said.

但这名官员表示，拜登还将讨论两国之间的分歧，以及如何处理这些分歧。这位官员说，其中最重要的是美国情报部门关于中国正在支持俄罗斯国防工业基地的报告。该官员说，美国已对中国实施了数百项制裁以防止这种支持，拜登将向习近平提出这一问题。

It is not clear how much Mr. Biden will seek to discuss Mr. Trump’s return with his Chinese counterpart. The U.S. official declined several times to comment on how Mr. Trump might try to reverse Mr. Biden’s approach to China. But the official said it will soon be up to the next president and his team to grapple with the series of complex issues related to that country.

目前尚不清楚拜登将在多大程度上寻求与中国国家主席讨论特朗普的回归。这名美国官员多次拒绝就特朗普可能会如何试图扭转拜登对中国的策略发表评论。但是这位官员说，很快就要由下一任总统和他的团队来处理与中国有关的一系列复杂问题。

The official said there is a “tough, complicated relationship” between the United States and China and that Mr. Trump will have to try to find an effective way to manage it.

这名官员表示，美中之间存在“艰难、复杂的关系”，特朗普必须设法找到一种有效的方式来处理这种关系。
