关于出现在不定式之后的while引导的并列句的问题

The pledge by China's top leadership to unleash the positive role of private capital while preventing its unchecked and reckless expansion has underscored top policymakers' desire to refine capital regulations to revive investment activities amid economic downturn while ensuring fair competition and better protection of public interests, experts said.

请问这句话中的两个 while 引导的是并列句吗?

while+doing形式为省略了主语和be的时间状语从句,修饰to do不定式,是不定式的时间状语,为不定式短语的内部成分。
