The data breach at Marriott's Starwood hotel chain that exposed the personal information of as many as 500 million customers was the work of a Chinese intelligence-gathering effort that hacked health insurers, other hotels and the security clearance files of millions more Americans, the New York Times reports.

Why it matters, from Axios' Joe Uchill: Tying the Marriott hack to the Chinese adds yet another layer of strife to the charged U.S.-China relationship, which already includes allegations of economic espionage, a Chinese executive arrested for violating trade sanctions and a burgeoning trade war.

The Chinese connection raises more doubts about prospects for a trade truce between China and the United States.

  • Following the G20 summit, the U.S. and China reached a ceasefire in their ongoing trade dispute after the Trump administration postponed a plan to increase tariffs while trade negotiations continue.
  • Trump said Tuesday he might intervene in the case of the arrest of Huawei's CFO in Canada.

What's next: The Justice Department is expected to announce new indictments against Chinese hackers working for the intelligence and military services, the Times reports.

Former New Jersey Gov. Chris Christie is seriously considering running for president in 2024, three people familiar with his thinking tell Axios.

Driving the news: While Christie isn't saying anything publicly about his thinking — besides telling radio host Hugh Hewitt he's not ruling it out — people close to him have an early sense of the rationale and outlines of a potential candidacy.

Chinese President Xi Jinping will attend President Biden's virtual climate summit this week, according to China's foreign ministry.

Why it matters: It'll mark the first time the two leaders have met face to face — albeit virtually — since Biden took office. China and the U.S. are the world's two largest carbon emitters.
