Chinese Foreign Ministry spokesman Geng Shuang said the country has lodged a diplomatic protest to India over the drone violating Chinese sovereignty.
"The Indian UAV intruded into China's airspace and crashed recently, and China's border troops have conducted identification and verification over the vehicle", the Xinhua report quoted deputy head of the combat bureau of the Western Theatre Command's joint staff department, Zhang Shuili, as saying on Thursday.
The External Affairs Ministry said in a statement on Tuesday that Wang, along with Russian Foreign Minister Sergey Lavrov would attend the meeting on December 11 to be hosted by External Affairs Minister Sushma Swaraj.
The exact location of the area where the drone crashed or date of the incident was however not revealed by either India or China.
India has admitted that one of its UAVs ran into technical problems and accidentally crossed over the Line of Actual Control (de-facto border) before crashing in the Chumbi Valley in Yadong County, part of the Tibet Autonomous Region.More news: 'Black Mirror' boldly goes at Star Trek with 'USS Callister'
The incident comes months after a two-and-half-month long stand-off in Doklam along the border in Sikkim, close to the India-China-Bhutan tri-junction. India had intervened on Bhutan's behalf as Chinese building activities threatened "Chicken's Neck"- a narrow strip of land connecting Indian mainland to its northeastern states.
The diplomat added that the parties would discuss coordination of efforts within the UN, BRICS (that involves Brazil, Russia, India, China and South Africa), the Shanghai Cooperation Organization (SCO), the G20, the East Asia Summit (EAS) and the ASEAN Regional Security Forum.
"According to our information, Wang will meet with the top officials of India and detailed information will be released in due course", Geng said.
Wang's visit is regarded significant as it is first by a top Chinese official to India after the Doklam standoff which strained ties between the two neighbours. It is expected to be followed by the 20th round of India-China boundary talks in New Delhi between Chinese State Councillor Yang Jiechi and National Security Advisor Ajit Doval, who are the designated Special Representatives.
It may also allay apprehension about joining the proposed quadrilateral coalition with Japan, Australia and the U.S., which was seen as a move to counter China.
