In the United States, obligatory retirement based on age is flatly illegal and has been for a long time. In universities, tenure means that Faculty members can continue as long as they wish. Some of my colleagues are several decades older than I am and still vigorously active. On the other hand, in American universities the set-aside for retirement between employee and employer contributions is typically 15 or 16% of income, meaning that with reasonable investment by the time you approach 70 your income from retirement savings will be as large as the income you would have had, if you had kept working (Some people, of course, start drawing on retirement savings as they approach or pass 65 or 70, even though they continue to work.) Note that university retirement schemes in the US are generally based on guaranteed contribution, not guaranteed benefit, plans. Over close to 40 years in academia, the general observation has been that if you retire as you approach 70 your income will likely go up even not counting Social Security.
In 2015, the State Council, China's Cabinet, set 70 as the retirement age for academicians. ( http://www.chinadaily.com.cn/a/201805/31/WS5b0f4f60a31001b82571d585.html )
