China, North Korea, South Korea and Japan are all East Asian countries. India is geographically distant from and largely uninvolved in the territorial disputes and maritime claims currently receiving international attention in the region.
Information on anything that has happened in India lately? That's a rather vague question. If you mean border conflicts, India has major territorial disputes with China and Pakistan, with several wars fought over their control. There have been several skirmishes and firing exchanges at the India-Pakistan border of late, and tensions have risen as both India and China are rapidly building infrastructure within each other's territorial claims.
It's possible, as an absolute worst-case scenario, that nuclear war could break out between India and Pakistan and start a domino effect by roping in neighbouring countries, particularly China considering their relations with Pakistan.
US foreign policy is gradually shifting towards a strategic relationship with India and has become increasingly supportive of its interests, due to the country being a necessary counterweight to China's economic and military influence in Asia.
