BEIJING -- Compatriots in Taiwan will no longer need to worry about shortages of energy and other supplies after peaceful reunification, a mainland spokeswoman said on Wednesday.

Zhang Han, a spokeswoman for the State Council Taiwan Affairs Office, made the comments at a regular press conference in response to a media query about tight oil supply and possible drug shortages in Taiwan due to the conflict in the Middle East.

After reunification, the mainland can provide timely guarantees for Taiwan's energy and resource security, industrial production, and material supplies regardless of external volatility, Zhang told reporters.

The two sides across the Taiwan Strait will establish connectivity wherever necessary after reunification, Zhang said, noting that the mainland's comprehensive industrial system and stable market supply can fully offset Taiwan's shortfalls in crude oil, natural gas, industrial feedstocks, and other areas.

Zhang slammed Taiwan's Democratic Progressive Party (DPP) authorities for showing neither the will nor the capacity to address the island's livelihood crisis, choosing only to evade responsibility -- a stance that has long drawn strong dissatisfaction across the Taiwan society.

The DPP authorities' claim that "oil and gas supplies are secure" in Taiwan is nothing more than self-comfort over their inability to supply fuel and, worse, a deception and insult to the public, Zhang said.

Emphasizing that peaceful reunification will create enormous opportunities for Taiwan's economic and social development and bring tangible benefits to Taiwan compatriots, Zhang said the earlier reunification is achieved, the more it will benefit Taiwan's development and the sooner Taiwan compatriots can enjoy better lives.
