having carrier battle groups is fair enough but they also need "friendly" ports to visit, resupply and re-fresh
I think Gwader is a perfectly located naval port from where China can project power into the Persian Gulf and the Arabian Sea and will give it easy reach to the West
a few years ago a Chinese naval escort force of Type 54A frigate, Type 05B Destoyer and a replenishment ship visited Karachi and rasied many eyebrows
I hope in the future Chinese naval vessals make more frequent visits to eventually station some of its fleet overseas, a SSBN stationed at Gwader would send shock waves around the region
The problem with a PLAN base in Pakistan is Pakistan.
It is too much of a geopolitical hot potato right now. It will exactly raise too much (Indian) eye brows.
and the "Grand Strategy" of china right now is button-down and hum-along.
10 more years of 8 % growth and its economy will be doubled again. that means (ultra-conservatively) 2x the government revenue. that means at least 2x the PLAN budget.
a low level prescence in somewhere like a Seyechelle or even Somaliland would be a better choice for right now.
The real external support from china, to pakistani external security from the its eastern side, is Chinese airforce bases in Xinjiang, Tibet and Yunnan.
