Invaded Chinese sovereign territory during the Korean war and got beat back into the current border of South Korea.
Supported a western friendly government during WW2 to take over China.
In International relations there are no rules.
"After the first two months of war, South Korean Army (ROKA) and the US forces rapidly dispatched to Korea were on the point of defeat. As a result, the ROKA and US troops retreated to a small area behind a defensive line known as the Pusan Perimeter. In September 1950, an amphibious UN counter-offensive was launched at Incheon, and cut off many KPA troops in South Korea. Those who escaped envelopment and capture were forced back north. UN forces invaded North Korea in October 1950 and moved rapidly towards the Yalu River—the border with China—but on 19 October 1950, Chinese forces of the People's Volunteer Army (PVA) crossed the Yalu and entered the war.[51] The surprise Chinese intervention triggered a retreat of UN forces back below the 38th Parallel by late December."
I can't find anything related to US/UN forces invading. But this is most likely a western view of the war. China looks like anything but just standing idly by during the war (did not realize that China was deeply involved in the Korean War before).

And if you insist on applying 18th and 19th century situations to current IP theft, then logically you should also be willing to accept what the British did to America: burn the capital. Is Huawei's IP harvest worth the torching of Zhongnanhsi and the Renmin Datang?
Yes.
> I thought America was the aggressor in that war and Britain just retaliated.
It's more complicated than that. Britain tried to prohibit America from trading with France, as part of their war against Napoleon. America thought that was against international law. Britain also had a habit of seizing sailors off of American ships and forcing them into service in the Royal Navy, which the US regarded as extremely over the line. The British were also (pre-war, IIUC) arming Native Americans on the US western frontier.
Eventually, the US declared war. But I'm not sure that makes them the aggressor, at least not 100%...
I am pretty sure US did not invade Chinese territory during the Korean War. There are a few instances of US fighters straying into China but pretty sure it wouldn't count as 'invasion'.
Did you mean when the US saved China from being obliterated by nuclear weapons by the USSR in 1969? Or when the US saved China from continued genocide by the Empire of Japan by almost single-handedly defeating the Japanese military in the Pacific? Maybe you mean when the US funded the build-out of modern China through trade & commerce and not only allowed them into the WTO, but openly invited them in (we got rewarded nicely for that).
> Invaded Chinese sovereign territory during the Korean war and got beat back into the current border of South Korea.
When the US tried to save the people of North Korea - the Korean War was a UN military mission - from half a century of extreme poverty, genocide and misery that continues to this day (and with zero human rights). With China on the opposite side of that equation, supporting the outcome of genocide, dictatorship, zero human rights, extreme poverty. Meanwhile South Korea became an affluent, liberal democracy.
> Supported a western friendly government during WW2 to take over China.
When the US tried to spare China half a century of extreme poverty, genocide and misery. China could have developed much faster and with human rights, as with South Korea, Hong Kong and Taiwan - and without the slaughter of tens of millions of people.
