How ignorant is you can be. Kazakhstan has been using the Chinese port in Yellow Sea for many years, You think Kazakhstan would use Chinese port if China doesn't have a well developed shipping industry and isn't a maritime giant, lol ? You think in war time, China has no navy, air force and PLA rocket force to destroy enemy forces such as your junk IN that dare to block Chinese shipping. Are you a fool to think China shouldn't develop connectivities with other countries for better trade and business and invest in other regions too ? Why China claim the islands in SCS even if some of them are closer to other countries' mainlands ? Simply, those islands belong to China. Why then your India claim to Nicobar islands that are just off the coasts of Indonesia, Malaysia and Myanmar but thousands of KM away from India ? Don't keep harboring stupid ideas and asking stupid questions that even a normal teenage would laugh off.
