He was quoted in Xinhua news agency as saying that India had "violated China's territorial sovereignty".
An Indian drone has "invaded China's airspace and crashed" on its territory, Chinese state media said.
The Chinese military alleged on Thursday that an Indian drone intruded into China's airspace and crashed. India had objected to the construction highlighting its security concerns.
India has yet to respond to China's latest claim.
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. "The two top diplomats are expected to sum up the results of the Russian-Chinese strategic cooperation in the outgoing year and exchange views on the RIC (the Russia-India-China format - TASS) issues and some other pressing worldwide issues", she said. The road was being built by the Chinese troops in the area which is also claimed by Bhutan.
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.
India's army chief said in Sept that his country could not afford to be complacent and must be prepared for war. "To the credit of the Chinese leadership, Beijing has taken note and started to adjust its diplomatic approach in recent months", he said.
Indian and Chinese troops were in a face-to-face situation near the Sikkim sector of the global border after the Chinese People's Liberation Army tried to build a road in Doklam in mid-June.
Starting in June this year, tensions flared again over a disputed region called the Doklam Plateau that borders China, Bhutan and the Indian state of Sikkim.
