Very sensible and logical conclusion. China can't win from the US militarily. Now add US, Australia and India in the equation and it's a lost battle. This isn't WWII that there are "blocks" to go against each other. Add Vietnam and a much stronger Taiwan in the mix too. It is wise to sit down with the US and talk trade and business and continue military modernization at a moderate pace as there is no way it can level (let alone win) with the nations I described above. The US has essentially built an anti-China alliance but only with much bigger nations to contain it easily (India, Australia for example and then there is the US and EU). Good article giving good advise to China.
I don't think you understood the logic provided in the article. Just like the top secret submarines being provided to Australia, let's assume if the US provides -35's to India, Australia and keeps a few squadrons in Vietnam and further strengthens Taiwan, this 300 number -35 force, essentially renders the PLAAF useless.
China is a "rising" economy. Not a global economic super power. The alliance against it, is the US, UK, India, Australia, all are extremely powerful economically. How many fronts will China focus on? To deter each of these, it would need $ 75-80 billion a year, take an example, India's defense budget is around this much while the US is close to a Trillion (times four, that's $ 300 billion plus R&D for future warfare, and then countering the US, etc). This arms race is MUCH more devastating for the Chinese than it is for the other 4 nations and 4 economies, vs. one nation and only one economy, i.e. the Chinese!
