Where can I find the original "On the New Rules for Destroying Countries" (1901) by Liang Qichao?

Actually, you can read 滅國新法論 (which Semaphore found) only in Chinese(unfortunately) at this site for free. The full contents is there. I can not read Chinese, so I can not help in anyway so you might need a help may be at Chinese SE.(Well...but nobody would translate the full content and the translation is mostly prohibited in many languages' SEs)

Yet, I would like to make some google translation and copy it here.

The New Law of National Extermination (Excerpt) Author: Liang Qichao July 16-August 24, 1901 July 16, 1901 August 24, 1901 Sister Project Sister Project: Data Items In today ’s world, the new world is also new: new ideas, new learning, new regimes, new laws, new craftsmanship, new armaments, new society, new characters, all the tangible and invisible things in the world, all unprecedented, And don't make a new world. The new law! Sheng Zai new method! Everyone knows it and everyone admires it. What we can't do is to say that there is a new law to destroy the country.

Those who destroy the country, the public law of Tianyan also. In the world, mortals must strive for self-existence, and for self-existence, there are advantages and disadvantages, and there are advantages and disadvantages to victory and defeat. For the inferior and the defeated, their rights must be annexed by the superior and the defeated, which is the principle of destroying the country. Since the beginning of the world, there have been human beings, following this day, fighting against each other, transmuting from generation to generation, only one hundred dozens of those who have been nationwide to this day. There are new ways to destroy the country, which are also caused by the common law of evolution. The former people regard the country as a family of one family, so the country that destroys the country must capture its monarch, ruin its palace, destroy its ancestral temple, and relocate its heavy weapon. Therefore, one person perishes and the country perishes. This is not the case now. The theory is clear. The people who know the country also have the public property of a country. Their relationship with the family is very shallow. Those who really want to destroy the country will destroy the country without embarrassing the family.

Restless, but often use the power of a family to help them destroy the country. In the past, the annihilation of the kingdom of mankind will be destroyed by the tart, while the present annihilation of the kingdom of mankind will be destroyed by the oh ye. The extinction of the people in the past is also sudden, and the extinction of the people is gradually. The extinction of the past is also evident, and the extinction of the present is also slight. The extermination of the past is also prepared for the people to know; the present extermination of the people is also brought by the people. The former annihilators are like tigers and wolves, and the present ones are like foxes. Or destroy it through trade, or use the main debt, or destroy it on behalf of the soldiers, or by setting up a consultant, or by a channel, or by inciting the party to fight, or by peaceful internal chaos, or To help the revolution extinguish. The essence has been exhausted, the opportunity has been cooked, or the name of the country has been changed in one fell swoop, and the color of its map has been changed; the unsatisfied and uncooked, although the name is still the same, it can be hundreds of years. Wow, the Thai and Western powers applied this new method to those who are weak and small. Yu Yu believes, please give an example:

The essay is indeed originally in Chinese, with the title 滅國新法論, which may aid further searches. It is collected in full in 《飲冰室合集》, as well as the 《梁啟超文集》 in abridged form.

The abridged version is available online from ctext.org, starting from paragraph 125. Wikisource likewise contains the same document. This version apparently excludes detailed summaries on the five examples of imperialism Liang gave, namely against Egypt, Poland, India, and the Boers, but otherwise retains Liang's actual arguments. This should suffice for most purposes.

The full version appears to be in《飲冰室合集》, which is unfortunately only available in snippet form on Google Books

Update:

Turns out《飲冰室合集》has been digitalised by the National Central Library of Taiwan. The essay in question can be found on page 32 (pdf page 34) of volume 3. Here's a screenshot:
